The new version of HP Tuners Rocks!
It's hard to explain how much better of a tune you will get on the road vs a dyno to someone who's never used HP tuners or LS1edit, etc however I can tell you that tuning on the road with a datalogger and verifying your changes with a Wideband is the ONLY way to tune for DRIVABILITY.
Dyno tuning pretty much consists of idle tuning, deleting codes, adding timing, and tuning the Power Enrichment (WOT) tuning. There is so much more to tune that cannot be done on the dyno (unless is a load bearing dyno), however most "dyno tuned" cars are ran on a dynojet.
Tuning LTRMS is a big part that should be done on the road with a datalogger, analyzing knock on part/full throttle, LTRMS, timing, torque converter lockup, line pressure,etc.
I guess what I'm trying to say is drivability tuning needs to be done on the road. It would take a few hours to tune a car the RIGHT way, but I can tell you it would be well worth it, after seeing some "dyno" tunes that people have had in their cars I really recommend getting HP Tuners or equivilant and tuning it yourself, you'll be much happier with the results (hopefully you can read and understand stuff).
Cheers.
