You may have found this out by now (if you did you can ignore this) the axle ratio 3.42 is the gears on your truck according to they make, year, and model info you input into the tuner. The tuner offers this function in case you decide to change your gears from a 3.42 to say a 4.10 gear ratio so it can calibrate the rest of the tune accordingly. If you want to see a big change in low end torque that 4.10 gear swap is essential. You still get decent gas mileage as the gear is very streetable especially with the size tires you have on your truck, and while you are under there I'd swap out to a 2800-3000 rpm stall converter as well. With just those two changes you can see huge gain in low end power and still cruise the freeways of SoCal with no problem with decent gas mileage.
@@MOTOPILOT6 If you have an automatic transmission, it is the connection point between the transmission and the engine (more precisely the flex plate on the engine) you probably have seen them before they kinda look like big doughnuts. They work on hydraulic pressure where they build hydraulic pressure as engine RPMs increase engaging the converter and transmission as the pressure builds, certain pressure they lock the transmission up to the motor generally close or at the point where the motor starts getting into its max hp range. Factory torque converters are set at a notoriously low RPM range (say 1200-2000 RPM). Locking the trans to motor outside of the motors HP building range on the low end which causes you to have to push the gas pedal down further while the engine lugs trying to get off the line or pull a load. A higher streetable stall conv (2800-3000) will help get the truck moving sooner allowing the motor get a lot closer to its hp building range with much less pedal especially on a mostly stock or all stock truck motor.
I have a tuned 2016 Silverado z71, stage 2 high performance transmission, running 4.88 gears front and rear. Lifted 9.5 with 37 toyo tires and 20x10 method wheels. I think this can help me even better
this video put me over the edge to take the leap and buy this tuner.. worked great! I had to buy an extra 40 dollar ecu unlock which I was not expecting but at least it worked smoothed the shifts out way better than stock
@@DM-qp7do I dont think you need it for your year.. i only needed it because it was a 2017 model or later that you need that extra file. So you should be good.
@@zoysiaguy3757 Cool, I wasn't sure what that was, honestly it sounded like some kinda California bullshit law that state would do to get money from ya haha. Thanks bro I appreciate the reply, im gonna try it out for a little more power and torque.
@chancellor9005 I'm not 100percent sure but I think it has cylinder deactivation that year too but I would look that up. You should be able to tell because the cluster usually tells you when the cylenders are dropping to 4 and back up to 8
It is a gear ratio. Different gear ratios are for different purposes. For example.... some gear ratios (3:42) are more for highway, some gear ratios (4:10) are more for pulling or "launching off the line"
@@paint4you792 idk if you already found out or not, but those ratios are the physical gear ratios in the rear end, you have to open the rear diff and change the gears to change that ratio
Go with a custom tune. These trucks are rich from factory, and a can tune that these have a general tune for all 5.3 /6.2. They are not all the same. And you can fine tune the trans better then the options you have. Also, leave the torque management on. It protects the trans. Diablew does them, its who i went with. Its 100 times better when you can data log in regular driving situations. Not WOT all the time. Drivabiity is important. Also having long tubes, exhaust, a good intake, cat delete is the best bang for your buck for hp, if thats what you want. Otherwise its the $$$ route. The tuner by it self is only going to make the trucks drivabiity better, but not knowing the timing/fuel trims. Why some guys are getting knock. A generic tune file. For a idea on times, with 3 in level 2" rear, 33s, 4x4, 3.42 gears, 6 speed, double cab, full tank, 91 tuned, i3 diablew tunned, and just the afe wet intake, carven r duel exhaust and my 290lbs ass, just so ya have all the info, lol does 1/4 at 15.46 @88.74. And 0-100 7.24. This is on a dragy. They are pretty accurate. Hope this helps a few people.
If you do 0-100 in 7.4 seconds then why does it take you 15.46 seconds to do the quarter mile at 88 miles per hour. I think your numbers are off my friend
I just bought this tuner. Do I need to get a cai with the tuner? Also I removed one cat since the Chevy has three. Will I need an upgraded exhaust too? Also I have a 6in lift 33x12.5s. What tune should I go with with this tuner?
I’ve had this tuner for about 6 months on my 18 Silverado 5.3. Have a 3.5 inch lift with 305s and 22 in rims with headers and full custom exhaust. I have it on the 87 tune and to me it is perfect. Shifts are on point and the throttle response is so much better with the full exhaust. I feel like to get more from this tuner is to have a better exhaust.
Love your vids bro, especially the VFR w/c I'm eagerly awaiting for the next one. I have a Pedal Commander for my '18 Tundra 4x4 and I'm very happy with it. It doesn't increase your horsepower but I'm very happy with the stock output anyway but the performance is like night and day! And it's way cheaper than the Diablo
plug your tuner into your computer with the provided USB cable it should recognize itself and give a prompt for updates. hope you haven't waited two months for this answer
Bro I just bought one of these. I tuned to the flex 91/93 octane tune. Turned up idle 100 rpm. Set the tires at 34.5 to fix Speedo. Throttle response at 15 percent. Afm turned to off. And on trans tune I did modify stock and just cut torque management off. It’s a big difference I’m get around 16-19 mpg on the highway depending on how I drive the truck and higher on the interstate. At first I did the firm shift but that felt like I was going to screw trans up even after modifying the rpm’s and shift feel it still didn’t feel right so I went back to just modify stock with torque management off. Trust me do this you won’t be disappointed… if you do throttle response to 20 you’ll feel it but you’ll also watch gas go away quicker. I’m on 325/60/20 tires your tires I’d probably put in 34.. if you do 35 speedo will still be off
I put a borla muffler on my 6.0 gas 2500.Throttle response went to mush.Borla techs dont believe me & say truck should adjust.With Stock muff had great snappy response.Also with borla engine tone sucks compared to stock.
I noticed it draws a lot of power from the USB port and would not work properly on my desktop pc. I had to update on a different device that provided more power to the USB ports. It would disconnect and reconnect quickly.
Fyi the dealership can see every time you've flashed your ecu. Thats just the way they make them now. I may be wrong tho I'm not a pro just my experience.
The fastest truck I've ever driven was a Ford F-450 rental truck from Home Depot about 10 years ago. When I was returning the truck I punched the accelerator at a traffic light and I was shocked that it burned Rubber and threw me back into the seat like I was driving an old 60s muscle car. I haven't been able to get that experience since I got the Silverado which just too mushy on the low end no torque at all.
@@seanpinal3709 he had the same tires on both runs. If he didn't have the tire size calibrated on the first run, and calibrated on the second, the speedo would have been underreporting on the first run, making it seem like a bigger gain post-tune than what it actually was.
You can’t buy the platinum if you live in California….but the difference is the standard 50 state legal allows some adjustments to your parameters the platinum allows you to load completely custom tunes if you wanted to do so…Platinum is what I recommend to everyone since it’s the same price does everything the standard one does but again allows for more tuning ability with custom tunes
How you got your diablo to work my diablo i3 is not loading up it asking me to upload it to unlock 17- up to tune my 18 silverado can you help new to the truck scene its use got it from a friend he sold his truck
It’s locked. Gotta buy a license. Ones you use these on vehicle they are locked to that vehicle. Have to buy another license to be able to use it on another.. then update it
I have the intune i3 and the engine tunes make my engine knock under load so be careful. iv tried different octane fuels i ran the 87 tune with 91 octane and it still knocked under load. i returned back to stock and no more knock but left the trans firm shift and AFM disabled.
@@s2knott My ears its audible and quite loud made me cringe anytime i heard it. i ended up removing the diablo device completely and no more knocking sounds.
You need to run your VIN and see what axle ratio (final gear ratio) you have and set your tuner to whatever gearset you actually have in your truck. Some of these trucks are 3.08, 3.73 or 3.42, etc....
Most gm vehicles have the rpo codes in the glove box. Could always check those. It should have codes for all the options on that specific vehicle to include the gear ratios

@@ryankobayashi13 great explanation! didnt know this. Thanks!
Change you rear gear to 3.75 it helps in take off . And that's a good hi way set up . 410 are moor race and stump pulling
You can also delete your top speed limiter. And I went with the Carven Progressive exhaust which is also awesome.
