My friend to look at these jet v plus modules. anyone have experience with them? gains?

nothing has been proven in the cobalt for them, my advise, its a waste of money, get urself a real tune not some "chip"

thats not true ask redssna

yea redssna (larry) has one and it helps. its just a basic tune that ups the fuel and timin conservatively. its not as good as a custom tune but it helps

You'd get better results with Trifecta tuning.

trifecta tuning i hear it everywhere. does anyone get any gains from this tune?

depends how much you have done to your car really ^


but you gonna get gains from a tune either way dude. Stock or modified
