Hey gang so as I've said in another post I just recently bought a 2004 GTO. Heads/Cam and procharger. 60lb injectors. I bought the car, did a couple of pulls, didn't notice any issue but they weren't long pulls. Just quick roll ons. About a week ago I was getting onto the toll road and got into it for a few seconds. And the car started breaking up. So I immediately stopped at an oriellys on my way home and got a fuel pressure gauge. Car was losing pressure under load very quickly. Which is the first video named "Needs more pump". I replaced the factory fuel pump with a Deatschwerks DW300C. Should be plenty of pump right? The second video shows I'm still losing pressure very quickly. The pressure gauge is hooked up at the rail. Let me know what you guys think. I want this car at 100%.
