Just got a Superchips 3875 for my 06 XK, 6" lift, 33" tires, 3.7L, QD1 (All wheel drive), drop in K&N, Flowmaster muffler. I know I need to change tire settings, speedometer settings, and I think I'm going to go with the "93" setting.

What settings should I set my transmission and custom items to for best results?

I'm not concerned with towing or 0-60 time. Just want it to get better gas mileage and put less stress on the Transmission. I don't want to use the 87 gas booster setting. I did that with an F-150 and it made it run lean and it had a rough idle afterwards and always seemed like it wanted to stall.

Any help would be greatly appreciated!!

Hi,

Are you sure that your Superchips 3875 is compatible with your Commander's 3.7 liters V6 ?

I haven't verified it with superchips yet, but I read somewhere it was compatible with all XK's. If not I guess I'll just post it on here. Probably won't be hard to sell.
