i love mine. worth every penny. i like how it can hold 3 tunes.
it takes a lot of reading on how to use it but after a while it gets easy. you can always fall back on stand alone mode where afr locks onto 12.8:1 and timing locks at 25* and then you just make adjustments from there. i dont use stand alone tho. technically i have it set to turn on at 6k rpm but with an aod trans, i never even get that high. there is a quick lean (or rich, cant remember) spike when stand alone turns on so some people like stand alone to turn on as early as 2500rpm (before boost kicks in).
