Performance Chip

[Core XK]

Yeah I am not really concerned with MPG as much. I mean...I bought a HEMI, lifted it, tires, and a roof rack. I have no problem paying for gas if I love what I drive. Anyway, it seems like the Flashpaq has the best overall reviews from you guys and others online. I am more so looking for throttle response, shifting, and tire adjustment. Is it worth buying these new? or is used just as good if I can find one? I'd like to get one later this year. I decided to only go 275/70/17 MTR's on the next tire switch just because I want the rear AC/Heat for kids (Which is going to be tried for in 3 months).

Adam, are the 275/70/17 a huge visual difference from 245/75/17? Because I am most concerned about that lol And I am sick of a skinny tire.

The only thing you get from buying it new is a higher price tag, and that it is guaranteed not to be vehicle locked. If you buy a used one and it's still locked to the old vehicle you will have to pay $100 to superchips to unlock it. I sold mine (accidentally) still locked and contacted superchips and they unlocked it for free though, because I had flashed it back to stock but apparently the tire size wasn't changed back or something simple that they could see I tried at least... So I guess if you buy a new one make sure it's more than $100 off new price, or be very sure who you are buying it from returned their jeep to stock.

Id actually suggest the Diablo InTune cause thats what I used on my XK and have it on my Ram now, its night and day difference on both vehicles. Ive got better mpgs and much better performance, but I feel it cause I drive that way!!! When I drove from NY on stock tune all highway I was avg 14.8, on my last trip to Darlington for the race I got 17.9 doing the same speeds, so thats quite the bump for my truck. The XK was only 1.5-2 mpgs but the throttle boaster and performance was a big difference. It had a lot of adjustable parameters that I liked as well.. either way definitely worth the moneysssss

We'll it's definitely a wider tire and taller at the same time. It will look good if you get the MT/R trust me
