Say I hooked a jet module to the computer and a hypertech programmer in the interior of the car.. would they both work? If so.. would I gain horsepower from both ? Hypertech the best way to go?

 

hypertech is an overpriced pos that will not gain you power.

Get a real tune.

 

Well I've noticed the hypertech does work that isn't helping me much.. I don't want to tune my pcm in case I do take something off in which it wont wont perform how it should. Anyone else?

 

None of those two will gain you any power you can feel and you should not use the jet chip with a non-stock chip. The Hypertech chip only changes the fan temps to kick on quicker, no power gains.
If you want to keep your ECM stock, but still want a chip, you can go with the piggyback option, which you can take off anytime and go back to stock:

so all the dyno's are bs for the jet chip?

 

i cant remember the site but search google for wait4me tunes the guy bubba is great. he gives you a completely custom tune on a new pcm so you get to keep your old one and then if you need an upgrade you just switch them out and send the old one back for the cost of shipping only. check it out. good luck.
