how worth it is it to get a tune for my '96 vortec 350 if i already have a hypertech programmer. is it worth it? let me know if you have personal experience.
well i was talking to allen a little while back...and he was telling me that with the obs trucks you hsould see the biggest difference with the tune. the NBS trucks computers are tuned a bit better than the obs trucks. and he was saying that the tune unlocks a lot of potential in the obs trucks
