I found an smt-6 on Ebay for 325.00, and I can get a VAFCII for 240.00 shipped. Besides timing adjustments, does the diff. in price justify going with the Perfect Power? I'm looking to purchse one or the other today.

 

well look at the price difference, if you are going to stay N/A and want the most power you absolutely need the timing advance as that's where the real power is from, the two guys who have tried the SMT6 have gained 9whp and 12whp from timing advance...one used 5 degree and the other 8 degrees respectively...whereas from a good A/F tune, you will only get maybe half of those gains
