SCT is SCT

the PRP is just the program that allows you to write your own tunes on your own computer at home instead of using a tune writer and emailing tunes back and forth.

it's nice to be able to write your own tunes, but the SCT software for dodge is confusing from what I understand.

as far as the guy writting the tunes not being at the dyno...as long as you send him the data from the dyno, there's no reason why he needs to be standing right at the dyno. Heck, I did my tuning on the road. I used a wide band O2 sensor and a data logger that reads Air/fuel ratio, engine RPM, TPS, MAP, etc. I'd go do a few WOT blasts on an empty road, send the file to Sean, he'd read it and adjust the tune accordingly.
