Increasing Gmc Yukon 2008 Hp

[denali200809]

So I recently purchased a 2008 GMC Yukon Denali under all of GM's wonderful discounts and rebates. I know that 2009 GMC Yukon Denali is virtually unchanged from the 2008, with the exception of an increased in horsepower from 380 to 403. It is the same engine in my 2008. I want to know if there is a way to increase the horsepower in my '08 to 403? Any suggestions would be helpful.

 

Thanks.

Probably won't happen, but ask the dealer to reflash your ECM with the '09 data

I agree. It has to be in the tune if they didn't make any mechanical changes.

Contact Justin at Blackbear performance. He will give you over the 403 and make it feel like 450.
