Hypertech Max review- not much to it
This is priced close to the big boy tuners but it only offers a couple tunes that relate to what fuel you use. It can adjust some other minor things such as tire size and what lbs your low tire alarm goes off at but I would not buy it again. Stock is fine compared to this and if you want a programmer, spend the extra couple hundred for the good ones. It will read codes which is handy and it will clear them - of course not for long but that part is handy at times.
