i'm still having strange fuel pressure readings.....i tried to lower my fuel pressure some and my car ran like ***.....it would hesitate really bad from a stand still so i bumped the pressure up to about 42psi and it works fine.....but i still can't figure out what could cause my other problem of my car hitting 80-90psi at idle.....what gives what could cause such a thing? could having my fuel pressure too low cause my car to freak out and spike the pressure like that.....or can someone give me some ideas...here's my set-up
zc motor
92-95 greddy kit
nos inline pump
vortech fmu w/12:1 disc
stock injectors

i'm also thinking maybe i'm having a problem with my injectors could my injectors be locking up from being abused and being old and worn....i have some bigger 310's to put in but i'm waiting for an 8:1 fmu disc.....if anyone has one i'll buy it

--i'm looking for all suggestions so if oyu have any iput please post
-thanks

 

Try swapping out your vortech FMU, I had one that went bad and whenever I applied any throttle it would read over a hundred psi on the gauge. I swapped it with a new one and the car runs fine now.

 

I hate to stay it but its defenantly warranted....GO STAND ALONE....its the difference between total **** and chocolate. I tried so hard (almost every weekend spending 4 to 6 hours a day) trying to get it right without a stand alone and it would always bog or hesitate somewhere ....with a stand alone...COMPLETE CONTROL!!...Hesitation? only a couple of minutes fix...compaared to a couple of days before....its worth the investment...stop trying to fool you stock ECU into thinking your car is still normal when its been radically modified...get an ECU that is smart enough to know what you have!!...My 2 yen

 

yea i'd love to...i gotta start saving some cash ...but anymore ideas?
