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!

 

Very impressive!! What other mods and how much boost? Was this a stock 5.7?? More info!!

 

Nice work !

 

More info please.

 

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.

 

compression??? Come on man, spill the beans. You cant tease us with numbers like those and not expect an onslaught of questions!!

 

Nice numbers. Now none of this,

 

I will get more info for you tomorrow. We didnot do the motor. I believe it is about 9:1 or so.

 

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