    Default G-Force performance chips 70$, junk?

    I was looking into buying a chip for the truck, and then I ran into this ad about 5 minutes ago. Anybody use these?

    yeah I wouldn't even consider it they are a scam that kind of power and fuel gain is to good to be true, if it where the big companies like hypertech and diablo would be out of business. you would be better off looking for a tuner on craigslist if you don't want to spend 300 dollars thats what i did i bought my hpertech for a hundred bucks of craigslist

    What they don't tell you is that you can make that type of HP under PERFECT temperature conditions, if you have every imaginable performance mod and you have the truck tuned. Diablo claims up to 20HP gain, that is a realistic number. Like Z71FTW said, if it worked that well then the major handheld programmer companies would be out of business. Also, if the MSRP is $400 and they are selling the product for $70, there is something fishy.
