if it helps heres the list of parts i have on it...
apexi, exhaust apexi intake stage II 16g upgraded turbo and a ems piggy back system that now controls the boost and fuel and everything...thanks for the help...

Did you rewire the fuel pump too? The stock wire is like 18ga iirc so maybe it's overloading the old wires, also you need a fpr with a 255lph pump.

You're running too much fuel pump for the stock fuel pressure regulator. You will need a FPR that lets you raise AND lower the fuel pressure in order to control it. You have too much fuel which is why your car is stuttering under boost at certain rpms. I'd change your plugs when you add the FPR, you likely have fouled them.

testing sig

ok thanks for the edvise also what kind of FPR do u think is the best for the money..?

Aeromotive

ok cool should i get her tuned after i get it?

You shouldnt really need a tune if your still on stock injectors IMO. BTW whats a stage II 16g?

lol someone better tell him the stock Fuel Pressure... so... Its 33PSI with the vacume hose attached... just... so you dont blow anything up mr. Stage II 16g...

Stage II ??!?!?! Hmmm, maybe I need one of those.

:rofl: Go easy on him guys ;)

Yeah, dont F around with anything other than Aeromotive. Wont need a tune unless you get new injectors.

Also, your sig pic is fuckin huge, scale that shit down a bit.

I'll show you that the MR-FPR is as good =P you just wait.

:iamwithst


Aeromotive is top quality bar none the best period IMHO. If you go with them you will never look back.:smooch:

i like his car, the color is neat! Wish i had a turbo.. wait i did.... wayyy too much work for me tho!

You got rid of it already??

My car doesnt sputter yet with just the 255. Only reason I got the 255 is b/c I bought my whole fuel set up off another dsm'er so I said give me it all. I might switch to a 190 or go with FPR. Im still undecided. I did hear that the automatic stock fpr is a little different than a 5 sp. Not 100% pos. though. Any thoughts?

It is under factory specifications.

stage II 16g is what the guy told me he had put on it inplace of the old turbo and since i just got the car i hadnt had time to research it...talons and eclispes are new to me i was more of a supra guy before i blew her up. ill change it.
