wow what a nice setup, i went with a 4 position high idle, 50hp, 100hp, 140hp. truck really rips on the 140 setting, puts out a nice amount of smoke too. engine and tranny definitly work better with this one in there compared to the old one. around town i leave it on the 100 setting, tranny is a little smoother and the truck is a little easier to drive (not as snappy). i couldnt be happier, and its good to know i could have custom stuff written onto it if needed. definitly suggest this to you 7.3L guys. on a 70-100mph run on the highway my EGTs barely hit 1300*F and thts with a stock turbo back minus cat and muffler, so the EGTs are pretty safe too. im ordering a 4" turbo back tomorrow which should help it breathe a little better then its off to the track again for some new numbers, maybe ill break 15s??
