I can't speak for Glen, but I am also going to be going with the InMotion tune once I get my junk situated. Will we be paying for another tune? Yes, unfortunately . I have nothing against Jerry or the LET tune as it is a good tune and has produced some good numbers. It's just not as proven as the InMotion tune IMO. I have looked at a handfull of guys with the InMotion tune (Needswings, MDSRT6, Cruzin etc...) and these guys are running great times and more importantly, crazy trap speeds (116-119mph)! I believe im one of the fastest LET tuned SRT6's and im no where near those numbers. Right now im trapping 113 consistantly with 114 being the best. I am running way lean at the top of 3rd which is not good and probably causing some of my low mph's. Also, I believe that InMotion already was tuning a car with stacked pullies and a meth kit so it makes sense I should go this route as well.
