I don't think my thread in the GMT900 section has much interest anymore so I figured I'd throw this here where all the boost junkies hang.


So far the truck made 486rwhp/498rwhp with no meth injection on 91 octane. Had it up to 504rwhp but once the truck starts getting hot it would ping so the tune was backed off a bit. Turned the meth on and it dropped power by about 40hp so there's some playing around to do.

Solid numbers! You have pre-cam dyno numbers?

So it lost 40 HP with meth spraying?

That blower sounds nice. Nearly 500 at the wheels that must feel badass when the pedal hits the metal.

Pre cam was 434rwhp/435rwtq but I also dropped from a 3.65" pulley down to a 3.25"

Never got around to setting the Alky Control module under the dash, it was more than likely dumping a ton in on the factory setting.

Not sure why it would lose power with meth. Did the logs look weird?

If you spray a decent amount of meth and do not tune for it then it will be way too rich and loose power.

What was your before boost and then after with the cam and pulley swap? Also what is your alky kits gain **** set on? The **** that goes from 1-10.
