Ok, did a search but could find exactly what i was after so, I got a malpassi sitting here in my room, and im wondering if i should put it on my car or not or if its worth it. my setup so far is: stock turbo motor, stock t3, injectors ect. only mods are, FMIC, 3" exhaust from turbo back, and a dual stage boost controller runing 12psi on hi boost setting. I have a Hi-flo that im going to bolt up some time in the future aswell. Anyways was wondering if I should put the malpassi on it or not, i thought it would help out with tunning ect, so it wont lean out ect. but i spoke to Rajab racing the other day and the bloke i spoke to said that theres no point in putting it on for my setup because it will actually make it slower or something like that?? so yer just let me no what you guys think, because if its not worth it ill just sell it. cheers Jay

No point dude.. only reason you would put this on your car if you needed more fuel to the injectors which usually means running a bigger turbo.. Reason why it would make the car go slower because it would probably cause your car to overfuel and run to rich.. To tell the truth i dont know many people who run Malpassi Fuel Regulators.. most of them have bigger fuel pumps and bigger injectors..

Malpassi's are **** if it was made in the last few yrs They simply dont flow the amount of fuel needed

so what are people useing as the standard fuel pressue reg is good for a 10 but i still wouldnt risk it at that, so whats the in thing so to speak?

ok thanks guys thats all i needed to no. i just saw that dixie, and a few other guys were running one and I thought it was a good thing to have.

every fuel reg rising 1psi FP to 1psi boost, some raise at more, aftermarket regs allow u to dial more pressure if u are running out of injectors but then u flood the rest of the fuel map unless u can tune it for higher fuel pressure. so on a standard setup which cant be tuned it will probly be more a pig and use more fuel.

unnecesary. and wasnt the reg causing massive probs on dixies car?
