- Most recent build (cam, pistons, bearings, machining, all gaskets) was done at rpmmotorsports.... Supercharger, headers and exhaust have been on truck for many years.
Since this is all time AWD, finding a dyno was challenging. National Speed in Richmond was the closest I could find to the Raleigh NC Area. nationalspeedi... They were able to get an additional 50hp at the wheels which equates to about 67hp at the crank during this tuning session.
The GM 6L80 with BW4485 Transfer Case consumes about 25% of the HP on the way to the wheels. I have seen a few people switch this to another transfer case to go rear only, but launch in AWD in an incredible advantage and I plan to keep it AWD.

Hello, where is your shop located would love to bring my 2007 gmc Yukon Denali Xl to get tuned.
It is in Richmond VA. National Speed.
@@fredleydiyI'm in Richmond haha. Scary to think such a stock looking SUV is roaming around like that
Stock transmission?
Mostly with 200k+ on the gears. It has a triple clutch torque converter and a deep cast aluminum transmission pan. The front and rears diffs are stock and the AWD transfer case is stock. Those three were rebuilt with stock like parts.

If I go up further in power, I will probably have the gear set replaced first.
How fast
