hptuners doesnt offer tuning for lt1's & tunercats license sceme is far cheaper once you actually buy the pkg...thing is I have about all the licenses I need IE all ls1 fbodies, all GTP's & a 97 v6 fbody license. I've never used lt1edit but I will say it(tunercat) doesnt look like a very sophisticated system. I just know read/write times are just as fast as hptuners & licensing is cheaper. It has 99% of the parameters I'd need to tune what I'd need to tune & at least they offer tuning for obd2 lt1 cars & not vin locked like edit. Again downside is the initial investment for something that i may not use very often in the future. Remember even the last lt1 that rolled off the showroom floor is now nearly 10 years old. And the only other licenses I might want with tunercats is the 04 gto & maybe vettes, but vette guys scare me.
