How much power do you normally gain with a flip switch tune (DIABLO)? if any? I'm getting that done to my car and I'm wondering if there is going to be a power increase...I'm getting a motor tune and a Nitrous tune....its a 97 Cobra..the car has BBK-LT's, JLT, 62MM T/B and Pro Flow 80mm and a 150 thru a C4 with 3800 stall...let me know if u got any info on it...TIA
