Hey peeps,I really need some help.Between shifts and sometimes even from take-off my car does not want to respond.I rev the motor and its like Its not getting fuel but then suddenly it revs or takes off while driving.I have a 94 gsr with a drag gen 3 turbo.Some have told me its because I am running stock fuel rail and regulator.any suggestions would be greatly appreciated.
Also,where is the best shop in MD or VA to get the car tuned?

 

The rail is not the problem it's likely the regulator. What type of fuel control are you using? More info on your setup please.

 

safc,stock ecu.bought the car used and do not know exactly what the previous owner had done.

 

you have stock gsr injectors?

 

SAFC should be fine, that's what I run but I also suggest a regulator. Stock injectors could definately be the problem. You sure there are no leaks in your plumbing or vacuum lines?

 

I think your problem is more likely the common honda stuttering/stumbling problem, a seperate problem, than your fuel system.

I don't think your fuel supply is going to "catch up" if it's being maxed out... right? no?

yeah, it could vary well be the FPR. its vary possible that your current regulator is not responding well when it sees no vacume and you car could actually be leaning out. or it could be the other way around and its dumping to much fuel in to soon and bogging it. you should have a friend follow behind you and see if a bunch of black smoke come out while its doin not responding durring exceleration. if so, that means your running way to rich. Also, you might want to make sure that everything is still calibrated correctly on your SAFC

 

Has the car been dyno tuned professionally? my cosuin thought he was the shit when it came to setting up the S-AFC (he has one on his boosted RSX) and when we took it to get it dyno tuned the guy doing the tuning gained him like 15HP throughout most of his powerband by playing with the fuel curve, etc.

 

double check all hoses for vacuum leaks

then look at your fuel supply

Could also be knock sensor? I'm having some similar problems on clients cars at the moment, I'm disabling knock sensor via custom ECU programs.
