Does anyone use the hypertech,or the superchips tuners etc.whats good

I don't know of anyone. I use HPtuners.

is that a hand held unit?

Nope HP Tuners is a software suite you run on a laptop hooked into the OBDII port. Does a good bit more than most of the handhelds

I would say that is an understatement Brian!

With handheld tuners, you are pretty much stuck with whatever parameters the unit can program.

With HPTuners, EFILive, the programming possibilities are almost endless. PLUS, you have FULL scanning capability with unlimited storage(being limited to the size of a hard drive).

So, for another couple hundred bucks, you can get a full package. IMO anyway.

Well worth the money.
