Need to re-tune for an AFPR ?

Ok , I got a 255 awhile ago. I tuned the car for the most part, but now that I have the AFPR to put on will I need to re tune my car, or will it be ok. Thanks guys.

If you set your base fuel pressure correctly then you shouldn't have to re tune anything, however, I can almost garunte that you can get a better tune now that you have the afpr in the car. The 255 has the tendency to overrun the stock fpr causing the fuel pressure to fluctuate which can cause obvious tunning problems.

Not so much your WOT tune but you should re-tune your low to part throttle.
