Help, DSM walbro 255 installed, now bogging
I just installed a walbro 255 LPH fuel bump in my 99 GSX. I have a turbo back exhaust, big16g turbo and tubular manifold. the car drives fine when not building boost but after it goes above a few psi it starts bogging and hesitating, it also feels like it's lacking power and if I really get on it it will backfire. Am I getting too much fuel or too little? I also clamped the fuel line coming into the fuel rail with a pair of vice grips but I didnt cut it all of the way off, this seemed to help a little but im not positive.

stock regulators have worked fine with 255s for 15 years. I don't see them suddenly becoming incompatible.
Did this start only when you changed pumps? If so you either kinked the hose or or the O-ring is not sealing. I doubt it's electrical because a short at the pump will shut the car off electrically.

P.S. - I just picked up a universal AEM AFPR from millenium as soon as i can get a fuel rail with an AN fitting or an adaptor I can install it and try it out.
Also is it possible the motor is dying from running too rich? and only stays running when i rev it because more fuel is required?
P.P.S. - also i noticed this time around the exhaust seemed to pop gurgle and crackle alot more, could be cause it's running so rich right?
