Ive been having problems with my car sputtering and stalling out when I gas it. I think its cause of the adjustable FPR i just installed. The motor was tune with the stock FPR which is at 40PSI stock. Once I installed the adjustable FPR, I turned it up to 45PSI, do you think that it is the reason why my car sputters and dies? That there is to much gas going into the motor than before?

Also if the car was tune on 40PSI, does it need to be re-tune at 45PSI to run right?

 

I dont think you should be changing the FP after the tune. From what I've read about tuning, that is one big no no. The ECU is tuned to whatever FP you are set at. If you change it. It also can go rich or lean out.
I almost did the same thing also.

 

oo i see, so i should just install the stock FPR back in.

 

Yup,
I had mine set at 65psi and my buddy said thats to high. So we adjust it back down to 45 and when I rev my motor, the FP goes down. LOL Called my tuner back and he said, "keep it too where ever it's tuned at."

just try what you said and see if the car is back to the same.

You need a retune if you want that FPR. That wont even take long to retune for something like that.

 

yea im just gon do that and see then.


thanks

 

Yah definetly switch it back.
