Fuel Maxx performance chip for grand cherokees?!?!

Anyone here know anything about this


Ran across it browsing ebay for Grand Cherokee stuff. I would think it isn't going to do what it says it will do....specially for just 23 bucks. Also don;t even see a how you would install it by just looking at the picture.

P.S. i know the auction has ended, I had book marked it a few days ago

2000 Grand Cherokee Laredo, V8 4.7, Quadratrac 2 TC, 255/70/16 Uniroyal Liberator AT tires with stock height, Flowmaster Super 40 muffler

Scam, BS, will actually do harm to your engine. Just like all the rest of them, it's just a resister that overrides the proper input from the IAT sensor to advance the timing slightly. They're all the same, no matter what they say.

I realize that this is an old thread, but just in case you are thinking of trying this out, the original product mentioned was on eBay, and while doing some research, I found this disclaimer on eBay's site:


Now why they would allow the people to run such a business on their site when they know it is trash... well, I DO know why... Money Talks, but at least they do warn people that it is trash even though you have to look to find the warning.
