I am going to put a JWT ECU on when my kit is installed. Then I will be at Stage III on my NA. From what I have read, I would be pretty much be wasting $$/HP to go any further. I definitely do not have $$ to go TT any time soon. UD pulley is an idea, but w/ my stereo I am scared of pulling too many amps for it? If you have any specific ideas, I am definitely listening..... -Brian
