Guys, I loaded in the TNT tune and now when i launch it from a stop and it hits 2500rpm in first gear it pops through the exhaust like a miss then it pulls to 3300 and shifts. The same thing happens when I am cruising at 55 to 60 and it downshifts and it will pop and then shift. Any ideas???

Also, when I turn the injection pressure up, I still can't get it to go past 22,800psi. I saw a qucik spike to 24,000 once. I'm thinking relief valve going bad, or my fuel pressure just isn't keeping up with the demand on fast throttle input.
