I saw this ad on youtube for this http://www.gfchips.com/jeepcherokee.aspx it seems to good to be true, I was wondering if anyone has it or knows anything about it, thanks

 

Its a scam had the same deal from another company on my tahoe. It was to good to be true. Waste of time and money.

 

Definetly good to know, think ill go jet!

 

It wires to your IAT sensor (Idle Air Temp). It then fools the ECU into thinking colder intake temps are present, thus making the ECU advance the timing and richen the air:fuel ratios. It will give you a very slight boost in power, but not much, and at the expense of lessor gas mileage (probably).

 

All that 60 hp claim stuff is for the big 7+L turbo diesel trucks. For the rest of us, these gains are PROBABLY going to be nominal at best. Even with a
company like Jet.. My roommate is thinking about one for her 2.0 NA VW, so of that happens I will think about posting it on here.. Also.. Your supposed to drive like 100 miles before it fully effects performance.. Idk.. Money back guarantee, so either way...

 

This. Performance chips and tuners do very little for the 4.0 unless you have a lot of other mods. I've seen 7.3 powerstrokes make 450+ HP off of a few simple mods and a good tune. Unfortunately, that isn't gonna happen with a 4.0. Spend the money else where, on something that's worth it

 

Thank you, true money back and its "marked down" like $300 id like to see a 4-7 mpg increase haha that just seams like a lie though

 

Anything marked down this far makes me think it is a total piece ...
