gobigorgohome 08-15-2006, 01:31 PM for the most part when tuned with my hypertech my truck is actually slower, sometimes it will pull a little harder when it downshifts but thats it. i put my truck back to stock and it atually runs and sounds better, did i get a crap programmer, truck drives different evrytime when tuned. redfish 08-15-2006, 10:53 PM Not sure what ya got, mine works very well indeed. Call Hypertech.....Did it load correctly for ya? IMHO i think you may have a junk one. Unit453 08-15-2006, 11:22 PM What level did you put it on? You put it on level 3, there is no mistaking that its faster than stock. Bodysurfer 08-16-2006, 01:06 AM What level did you put it on?

You would absolutely notice a difference even on Level 2. Unit453 08-17-2006, 12:53 AM Something is definately wrong then. You would absolutely notice a difference even on Level 2.
