Default 480rwhp and 550+tq Denali
We completed tuning on a 2005 Yukon (converted to a Denali) with a 5.7L engine and STS kit with FMIC. We used the HP Tuners 2-bar, speed density programming and the driveability and fueling issues were completely addressed.

Bigthanks to "Plan B" from Australia for spending some time with us and showing us the ropes on the SD tuning.

HP Tuners is now available at Fastech for all year model trucks!

05 Yukon with a 5.7? Am I missing something? I didnt know that they had a 5.7 available in the Yukon, is it a aftermarket engine?


Or was it just a typo?

It is a forged internal 5.7 so we could run a bit more boost I knew that would raise a few questions.

I'd really like to know more about the speed density tunning you did on this.
