BEST B7 RS4 UPGRADES: +100BHP WITH ECU SOFTWARE TUNING [PART 3]

Part 3 of the B7 RS4 upgrade series! In the latest video we finish off the transformation with our ECU software, tested on our in-house dyno for accurate results. Having undergone a full decoke/carbon clean and a new Milltek exhaust system fitted, the RS4 saw a +100BHP increase after our ECU software - a colossal improvement!

I don't know why people are saying stick numbers, you've got over that at the wheels! You've killed it guys, my dream car but sedan haha

[@RegalAutosport]

Thanks!

[@V0L0DImer]

My car is barely showing stock numbers after ecu and exhaust tuning as well but it is still awesome 😅

[@RegalAutosport]

Yup! These cars never made stock figures straight out the factory, so its all relative

[@agaloodyowie1]

What tail lights are they running? Sick gear guys

[@RegalAutosport]

Thank you, and I do not know

[@claudio6175]

Surely the carbon clean alone would get it back near original power of 414 bhp?

[@RegalAutosport]

Depends on so many variables, we don't fake the numbers

[@RSTHOR13]

What time is this ?

[@RegalAutosport]

Time to party

[@mikemayers9353]

So its leaving with oem power

[@Habby-st2cz]

@@RegalAutosport that's rubbish about it being relative. You only have to look at other mappers (e.g. MRC) to see plenty of carbon'd up examples that come in with super low power, low 300's in some cases, then they leave with 440+bhp.
Stop trying to tell your customers that it's normal to only see stock figures after a carbon clean and a map. That is absolute nonsense.

[@Habby-st2cz]

Your tune isn't very good. MRC and QST for example are able to get 440-460bhp with a carbon clean and map.

Thanks for sharing, it's worthwhile taking into your sharing that you can't compare dyno figures from different cars, running in different operating conditions, using different dynos, using different dyno software, to name a few factors.
But anyway, thanks for your comment which is not fair and balanced.
