Adjustable Fuel pressure?

[mustangfan1990]

Since I am going to get my car tuned do I need an adjustable fuel pressure regulator since I will be doing away with my FMU? Right now the stock one is on it

if your getting it tuned leave the stock regulator on. a proper tune is going to tell the EEC what size injectors you have and if you jack up or lower the pressure the injector will essentially become larger or smaller and either make the car rich or lean and the computer will start trying to compensate. its just easier to leave it stock.

cool thats what I wanted to hear. I am SOOOOOOOO tired of spending money on this car right now lol I an getting burnt out and BROKE ....lol I just ordered the 2.75 pulley and getting ready to order the SC belt as soon as I find out what size I need and the 600 for the tune and I am done for a while.

A good adj FPR is a good upgrade, they tend to be more consistant then a worn stock unit.

That and they are not super expensive.
