Has anyone tried this add on Module by Power Max for their 3800? I found it on ebay for $20 shipped to the crib. item # 231182553632 if wanna check it out on ebaymotors. Lemme know what ya think cause for that price it would be worth any gain at all!

 

if you believe any of those fake modules I feel bad for you. they're all fake. don't waste your money on any of them. if you want real power then pay the $$$ for decent stuff for your car.

 

That "chip" is a cheap Radio Shack resistor put inside a fancy package. You splice it inline to the intake air temperature sensor wire, and the resistor makes the computer think the incoming air is colder than it is. That then richens up the air/fuel mix, which, really makes it baffling to see how it makes you "save fuel". Don't waste your money. If you want something that gives you the same performance results, rub a rabbits foot on your engine!!!
