Don't know if this helps, but I have experienced something that might explain your issue. When I am on the interstate and give a moderate stomp on the gas, sometimes I don't get all the "boost" from the tune. but, when I slam the pedel down the power is there. this happens to me at all speeds and power. To me it seems there is a "pre-requisite" for the GMPP Tune to fully kick in. I would be intrested if anyone else is having this happen to them.
To test, apply pedel to the floor in a controlled manner, then try stomping the pedel. if it is anything like mine, you will only get 15psi for a gradual increase in throttle.

MIne worked fine for a long time. Then one day, nothing. Stopped for a while, then it started working fine, for about a week. Kept goingaway, so i did not get it in to the dealer. Now i sometimes gets 21-22 PSI, 10-15 PSI or not over 5 PSI, just depends on how the time thing s feels today. HOPING the wire solder will cure. Anyone else have this intermittant sh**!

JJ like I said before buddy SOLDER SOLDER SOLDER. I had the same intermittent issue kept getting code P0238? I believe is what it was now. Cut Butt splices out SOLDER together shrink wrap, hold onto steering wheel feel the power at all times. My turbo sings all the time now. I got Secret Services to do it and retune, They couldn't just like me believe the butt splices was the issue. I also signed up (Gadget) for the class at http://www.grandsportspeedway.com/opentrack.html come out and watch. April 11th....So a fellow BRUDDAH some support

Better bring a lawn chair they have chairs but they are hard and uncomfortable. My gal will be there as well to watch....bring a igloo or something as well for drinks depending how long you'll be out there. I'll have one out there if you just want to bring drinks food etc....
