So I have the MPD 64.5 kit with full piping, tuning by NL. When I try to give it full throttle it initially feels like it’s making good power and then it feels like there’s a stall. Almost as if I was letting off the throttle a bit. As soon as it shifts to the next gear it feels like it’s pulling well again. What do I need to monitor rail pressure and what psi should that be? Just trying to decide if it’s tuning, transmission, or just because my HPFP is maxed out. Thanks for any help.
