Does anyone have the gforce chip or any chip for that matter and is is worth me spending money on one for the little performance boost but mostly for the gas mileage.

There is no chip for the HHR, only a handheld or a custom tune. There was one here getting a handheld, but haven't seen any results from it yet.

Best bet is a tune.

Tune seems the best way to go......I've read the handhelds are more money for less effective preformance......no experiance with either but a tune has always been the way to go for most all vehicles vs. chips or other items.

I've had tunes on other vehicles and compared to say a "Superchips" chip, the tune provides more preformance and gas milage for the buck.

I have Trifecta, Vince knows what he is doing.

I would spend money on a programmer(like myself) or a tune...just my .02

I'm wanting to tune mine, but don't have any trifecta dealers around me. Suggestions?

I would not mess with trifecta, on my supercharger project it took them a month to send me a half ass tune that was extremely lean. Sent them a data log and 3 weeks later he emails me about how the intercooler pump is wired. I email him explaining how it is wired and he never responded. I gave up on him a week after the last email. Got it dyno tuned and it was good to go besides the clutch. Overall trifecta's customer service was horrible. I sent them an email about once a week and never got a response. If I were you I'd do whatever engine mods you have planned and then find a good dyno shop
