Jet Performane Modules

Well I guess I can do that and if I don't see any improvements or not happy I can always sell it on here or ebay.

I've got one that's been used for 1 week that I'll sell.

Well I have had this chip for a week now. I'm running 94 Octane Sunoco Fuel. I have a stock 2007 Cobalt SS/NA 2.4L, Automatic.

Mods: GMPP SRI - Air Box Removed from fender - Jet Performance Module 'Stage 1'

So far I have not seen much of a gain in any form as they 'Promote the chip' to be. I have lost roughly 2 MPG on Fuel Economy and there is a very small amount of gain in torque/HP that can be noticed if it indeed exists. Dead stop runs produce about the same or a small gain of wheel spin which isn't much in Low with TC OFF. First gear still lags/bogs from a dead stop and hinders 0-60 time and speed just as before. Highway driving hasn't improved in the 'Performance' aspect either. Shift points are the same and are not any stronger than without the chip.

So this leaves me wondering why the hype over this chip? Second I am going to place a call to Jet to see if the module indeed goes in the middle pin-out on the PCM.

I'm curious also if this chip was designed with the intention that we the buyers have already modded our Cobalts with after market exhausts, etc.

My conclusion so far with 1 1/2 fill ups of 94 Octane Fuel is this chip was NOT worth the $239.00 I spent on it.

Yes, for those who may ask I did remove the chip and take a few runs without it and install the chip and run it again to see if I would notice this INCREASE in performance and to be honest it all could be in my head that I am seeing or feeling a VERY SMALL gain in performance.

Cal Jet Chip and ask them to take it back and check it out. You should be happy with it!

[KTOHIO]

Yeah, I'll have to wait till I get time on a business day. They are only open till 5pm M-F. It will be highly doubtful I will be able to talk to them plus there tech support isn't toll free and in Mich. ! ............

Jet Chip toll free number -- 1-800-535-1161 works for me.

You can try e-mailing them from their site, but they haven't answered my last 2 inquirys about their new performance control module.
