problem after increasing fuel PSI
yesterday i install an AEM fuel rail, a B&M fuel regulator, and a B&M fuel gauge. i boost the fuel psi up to 50 PSI open throttle(40 close throttle) car run fine. today i found a little leak around the fuel gauges so i take out the fuel gauges and put teflon tape around the thread. the leak went away, i also boost my fuel psi up to 55 PSI open throttle. i ran the car and the car start to boggle heavily at 4000 RPM when i punch it and press the gas pedal all the way down. it doesn't boggle if i lightly increase gas and drive normal, only happen when i punch it. it boggle like it hitting rev limiter, like it cutting off gas. i have intake, exhuast, smsp header, chip neptune Ecu. PLEASE help! it really bothering me and i want to go to street legal to drag tomorrow.

here...
turn...down...the...fuel...pressure....
your car is bogging because you are flooding the motor with fuel. You need to tune your car and adjust the fuel pressure on the dyno.

Put the fuel pressure back to stock that's how you fix it. MAybe get away with 2 psi over stock but you'll mostly be wasting gas to tell you the truth

Reset your static fuel pressure back to 44psi if you are on a stock ecu.
Resetting your ecu is not going to do anything. If you are running the neptune, you must put your fuel pressure back to what it was originally tuned for.

set it back to stock. you said you were chipped right? well that should have taken care of your fuel maps. you are just flooding the motor out.
