I agree. I believe the KB OPT II is the best way to go. I'm not sure what the gains are for the 3.2 but they show the 3.5 gained 10 hp and 10 lbft at the wheels. The biggest advantages besides the power increase are removed torque management, firmer/shorter shift points, lowered temp and t-stat mapping, and raised/eliminated speed limiter. Most people just look at the power increase but not the other factors and come to the conclusion that it is not worth $350 for an extra 10 hp. I believe that once all aspects are taken in account, the KB Opt II is an excellent value. It is almost transparent under normal driving conditions but once you open her up, it really reveals itself. It will change the overall personality of your car under WOT. Just be sure to get a 160* t-stat from shadowvox6 otherwise you will end up replacing your cooling fans in short order.
From what I have read and heard about Jet Chips from other LH owners is that they are crap. Some people claim that they actually LOST power! They may work well with some cars, just not ours!
