Can’t seem to find any solid info on how the high pressure fuel system works in a Gen 3 GT. Once fuel gets to the actual DI pump, it then pressurizes fuel further and sends it on to the DI injectors, does it hold that pressure for a certain length on time? What is normal pressure at idle? Where...

Recently I’ve been having problems with my car, found some exhaust leaks and fixed them up,(car is completely returned to stock with factory tune currently) asked a tuner to look over some data logs and got “something is wrong” but not any help on where to look. Car has flashing CEL with misfire...

Im fighting a misfire problem on my car and am getting an intermittent noise from what sounds like the HPFP on my 18 GT. Most times it’s there but sometimes it goes silent before coming back after a few seconds. I also took a datalog and was wondering if anyone with a better eye for it could...

Where would I be able to...

Hello everyone, just came across my first issue for my 2018 GT. Few weeks ago I left the car running and ran into the store for 5 min, came back out and the car had died. So I replicated the issue for a datalog and Lund said the intake cam phasers are going out and I do not have a CEL either...

Hey everyone, I’m new to the mustang scene and recently started doing some mods to my GT. Unfortunately yesterday I went to shift into 2nd gear and it wouldn’t go into gear at all. It just felt like it was hitting a wall, no grinding or anything and after about the 3rd try It finally went into...
