Hey guys, I have a 2007 gt. I was at the dyno today getting tuned for 150 shot. The tuner said that when the nitrous hits fuel pressure is dropping down to ten psi. But then it comes back up. He is concerned with detonation when it drops to 10psi. Mods are nitrous outlet plate kit 150 shot. Not sure what the jets are but is the ones recommend. Hot rod cams, long tube headers, frpp intake manifold and throttle body, roush intake, 39lb injections and walbro 400lph fuel pump. He is not sure what's going on with that big of a drop in fuel pressure. I have a track day next Saturday and I'm hoping to get it right by then.
