I bought this so called performance chip and yes it worked for about a month. I noticed a lot of improvements to my truck, then my truck got really sluggish and I worried something was wrong with my truck so I disabled the chip, drove without it for a couple of weeks and the truck came back to life. I did some more research on these ICs and they are nothing more than a resistor you can buy for a few bucks at a radio store that basically tricks the mass flow into believing it is letting more air into the system. So I experimented and reinstalled the chip and it worked very well again for about a month, after which the same events happened again. This is false advertising, this unit does not have dyno settings installed which will NOT change your MPG AT ALL and will not increase power or performance as I said from a few weeks to a month. The computer in your car falls back into place and the chip stops doing what it promised. To me it's a waste of money unless you're looking for something you can benefit from in a short amount of time like B. a one-night race. I hope this benefits those who ever try to get what they think they are paying for. Do your research first. I have been fooled and I hope none of you do the same. Revain should abandon this product completely! I only gave one star because it made me rate it but I put negative stars
