Was going to add some Ford gt fuel pumps and do the pprv delete and do the wire upgrade and a friend said I will need to retune cause of fuel voltage trims ? or something. Was also considering ditching my boost a pump. what do you think.
Yes that is correct, you will need to retune. I just recently installed improved Ford GT pumps and did the PPRV delete. The pump install was easy...the pprv was easy, but gave me a lot of issues. I had to drop the tank 4 times to figure out what the hell was causing my car to run so poorly and spit out fuel out the tail pipes. The lines were kinked, or came off the fittings, so I ended up hardlining all of the 180 degree bends and barely used any fuel line. I maybe have about 10" of fuel line. If I known I was going to go this route, I could have saved money not buying the pprv delete kit. If you need anymore advice, just go ahead and shoot me a pm. I'll be glad to help avoid the headaches I went through.
