Low Boost ???
Alright so I was playing around a bit with the chip and I turned it all the way off and I noticed at wide open throttle the boost built really quick to 15psi and then all of a sudden I heard it bleed off to 10psi and no matter what the throttle position I then turned the chip up to the 100hp level and did a half throttle run (cause anymore and the tranny will give me the finger) and the boost did the same thing. I am thinking a new aftermarket waste gate and boost code eliminator. what do you think

Re: Low Boost ???
I would check for boost leaks, 15psi seems alittle low. Even for a stock tune!

Re: Low Boost ???
i dont know what kind of turbo you have but 00strokey was gettitng 25.5 after his tune when he had a stock turbo. and i think the wastegate and boost fooler is a good idea.

Re: Low Boost ???
Check the boots and up pipes. I can hit 30ish in my 120 tune with a stock turbo, and yes its not good for it.
