Comp cam on 6.2 L92

[jshahin]

Dear Colleagues,

I have Yukon Denali 2008 - 6.2 - L92 - VVT.

I installed Comp Cam # 156-401-13, springs, and Phaser Limiter. My issue is that I couldn't find anyone the racing workshops can tune the GM computer. They are using HP Tuner but whenever they tune the GM computer, the car start to lose the whole car electricity.

Can Anyone guide me for a full proper tuning for my GM because I can't drive it for the time being.

Regards,

Juma

Juma I really could not tell what the problem is there. I would recommend maybe checking with HP Tuners tech line to see if they could give you some insight to would could cause that issue and also maybe suggest someone local for a second opinion.
