hypertech power programmer

Has any one used one of these?The only reason I'd like one is to firm up my shifts a bit.My question is does the progammer only work at full throttle or will it firm up the shifts all the time?And is it worth the money?tia

I belive it is worth the money ask anyone who has one man they are great you can feel the firmness of the shift i origonally bought mine to just take of the govener but man best $350 mod around

Very good upgrade for price. The harder shifts are noticable with/without full throttle. I had a 99'/5.3 With the programmer and a K&N Air filter, and the added horsepower/improvement in shifts were definately noticable. Its also awesome to get past the governor. I'd recommend both as affordable upgrades to your truck that dont require much work. :biggrin:

I added the power programmer III to my '02 Duramax yesterday. It took all of five mintues to program, and the difference was astounding. Additional power throughout the entire spectrum -- even off the line, which Hypertech doesn't really tout.

I'm pulling a horse trailer this weekend so we'll see how it does with 7,000 lbs behind me, but thus far I'm very impressed -- best upgrade I've done to date.

I know this thread is old but i got the programmer and it did just what i needed.Thanks for the input
