Here's what my car does. Whenever I get into boost the car falls flat on it's face. It's like it's trying to push a 18-wheeler or something. This happens right around 4 psi of boost. Is this fuel cut happening in a massive way? Driving an hour on the highway today I had to very gingerly accelerate up hills or the car would buck and chug all over the place. The car did this every once in a while before when the engine wasn't up to operating temperature, but now it does it all of the time. I have a stock 14B running off the 9 psi wastegate spring. The only mods I have are a 3 inch down pipe to a 2 1/2 inch exhaust and a KN filter. Should I try a different maf? I have a stock one from a 1st Gen eclipse in there now.
