Just installed one of TU's new 4 pucks with larger disc and "purple" plate. Pedal feel is better than stock and it seems to hold the power just fine on my car making over 500ft/lbs. I did have a slight spline issue like someone else on this site had, but 20min and a file and it was cured. Chris says the new supplier will solve this fittiment problem. I also installed one of their 3in down pipes and the fit and finish was PERFECT, couldnt ask for any better....same with the steel braided oil feed line from them. Thanks for all the help Chris.
