Hey guys. I’ve got a 21 Mach 1 with a D1X that I just recently had tuned on E85 at around 16psi the car seemed to be running great. Car made great power and everything was good. I was driving the car last week and it felt like something was way off with the car when getting into boost. I sent some logs to my tuner and everything looked similar to my dyno tune as far as fuel trims go. I never did rev the car out past probably 6k rpms. However when driving the car it’s surging, bucking, and feels way down on power. I’ve changed the plugs and inspected the old ones.
Now onto the fuel situation the cars having. I noticed that my fuel pressure gauge on the regulator is bleeding off extremely quick now compared to what it used to when shutting the engine down. Also when I turn my ignition on it primes and 10 seconds later it drops to 0 as well. I’m not sure if this is signs of a bad regulator or bad pumps. I feel like I’m battling fuel pressure issues but could be wrong. Any insight on this is much appreciated. I attached a short video of the gauge.
