Ok, so here's what happened. I installed the Boost cut defender and I also installed my boost gauge/ controller. I'm pretty sure i did everything right except i put the vacuum line in the wrong spot (I'll fix it tommorow). So I go to test out what all was different (if anything). I felt some difference not much so i left it alone. Now when i'm in 4th, 5th, or 6th I feel the motor cut out. which leads me to ask you guys whats wrong.
