I've uninstalled the hpp3 and resold it already.
I have a f-body and not a y-body but my opinion is if you don't have the cash to lay down for any other programmer and own an auto that's basically stock hpp3 isn't a bad way to go. You can pick one up used for less than $200 and sell it later on and get most or all of your money back. Just out of curiosity before I sold it I used the g-tech and made a run on it with the hpp3 then uninstalled it and drove the car around a while and made another run and was .2 & 1.5mph slower in the quarter without it. I'm ready to do bigger and better mods so the hpp3 isn't even in the same league with edit there. JMO
