I just purchased a used otc 2000......this will be my first scan tool....i would just like a few replies on what you all think about it...also from what ive read it pretty much does everything but moniter boost...i have a 87 gn.........one last thing if i had the money i would have bought a scan master ... but for the price of the otc i could not pass it up..... hopefully the otc can "tune" my car properly......
