I wouldn't trust it until I'd seen some evidence that it doesn't hurt anything and some dyno #'s.

 

ditto

 

buy it, let us know how it turns out.

 

this is pretty sweet, i would def test it out if i had the cash

 

That doesn't look safe, keep it away from me.

 

hm all the latest posts about the hp tuner software points to simply air/fuel modification I wonder if that is all that is going on or if there is more to it than that.

 

the JET Power Control Module (PCM) has a computer upgrade solution for late model GM vehicles without removable chips. The JET PCM provides the same type of Power Tuning as a JET chip and is the most sophisticated tuning device for late model GM vehicles available today. The JET PCM is a 20 Mhz RISC computer that controls air/fuel ratio, ignition advance and transmission tuning for the ultimate in power gains. Limited Lifetime Warranty! Easy Installation! Increased Throttle Response! Will Not Void Factory Warranty!

nto sure if its for the cobalt as it states its for late model gm cars..

 

I just called JET Performance Chips and they told me that this product will NOT work on Cobalt 2.2L....so in other words

DO NOT BUY THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

IT DOES NOT WORK ON COBALTS!!!!!!!!!

I'm gonna send Gravana an E-Mail with this information.
