The tune is the Zdyne converted files for a FI ZC. So I think they should make a good basemap. I'm pretty sure it's not the fuel managment cause I also threw in a rom with no boost (no extra fuel for boost) on it and it did the same thing when I tried to go into boost.

 

Air you using an air filter? Seriously, Mine did something like that. I could hit boost and then dropped out, bogged all that ----. Turn out that my air filter restricted the inlet ALOT. Enough to stall the turbo at 5psi and 4900rpm

 

Got it fixed! put a new o2 sensor in and took off the Half downpipe thing. I think the turbo was sucking up hot exhaust .
Thanks for all the help guys

 

Tight, im glad to hear it!!!! You think it was the O2?? i know mine is bad and that ---- if really ------- up.
