when i have the extreme rkl tunes loaded on my truck it pops when you get on it in 2nd and the begening of 3rd. when i turn on my quad pressure only box the poping almost goes away. not nearly as much poping/sputtering. my best guess is draining the rail. im adding a holley pump to add a little fuel flow to the cp3 but its not here yet. if im draining the rail should i have to worry about rail pressure? any one else have this problem and find the fix yet
