If you purchase a hpp used on this site, are you still able to use all of its function on your Computer. I dont want to sound retarted but i need to know cause i have gears going in this week and the Rep from SLP said the hpp is the only way to calibrate the gears to your speedo. Or is there another way. Please help!!!! gears go in next week....

 

SLP makes a speedometer calibrator. I think a few other companies do too. Just do a search on it.

 

And yes a used HPP will do everything a new one will do if the previous owner put his car back to stock settings.

 

good, thats so good info. I talked to the slp Rep they discontiued to speedo calibrater. I was going to do that originally!!

 

Just make sure that you get an e-mail or something form the person selling the HPP that says that the unit doesn't have any programming on any vehicles, otherwise it's useless, and they walked away with your money.
