I have a 2003 6.0 Powerstoke 6-speed. All I hear about is the SCT, but Ive also heard about tranny troubles with them, but I have a 6-speed so Im not worried about that. So Im pretty interested in SCT. Ive also looked at PPE, how are they? I also have a friend with an Edge Juice Platnium for only $500, and another friend with a Superchip for only $250. I know they will all give me good power output but I love smoke, will they all give me good smoke with a straight pipe? What should I do? P.S. Im on a tight budget.
