When I throttle my car, it sputters and then dies/stall out. I cant even get to 3000 RPM without it happening. At times when I stick it into 1st gear it will stall out too. It all started to happen when I installed the adjustable FPR, also one of my pins/wire came out on the ECU but it doesn't throw a CEL. The car is boosted and tuned, it has the right injector size for the power its making.

It shouldn't be the timing since it never happend before.

I think that its when I installed the FPR and turned it up to 45PSI but what can turning the PSI up do?

What do you think is going on?
Can it be the FPR or loose ECU wire?

Any kind of info be helpful.

If it was tuned why did you mess with it?

 

LOL, what I mess with?

I just changed the stock FPR with a adjustable one (AEM).

you said it was tuned....why did you change things on the tune?

 

Are you saying I cant change to a aftermarket FPR after the car has been tuned? Im sure I can. Its been tune for awhile even before the aftermarket FPR was installed.

So will I need another tune since the stock FPR was 40PSI and now the new one is turned up to 45PSI?

Yes. You changed something related to your tune. So now it needs to be retuned.

Upping the fuel pressure, will also up the amount of fuel going into the engine.

 

so the answer is to get another tune since there are more PSI of fuel going into the motor than whats it tune at and is that why my car dies out?

40PSI tuned on turned up to 45PSI = another tune?

 

Turn your pressure down to 40 psi, and put the wire back in. It's there for a reason.

 

alright let me do that and see.
