In Need Of Some Info Please

i have a 99 wj w/ the 4.0 and am wondering if anyone knows if theres a company that makes a chip or programmer so i can tweak my engine ? most are for the v-8's .....also i have a set of 20 's with 274/40's and i'm needing new shocks , so im thinkin that the weight of my wheels should be about what the 4x4 you guys drive and was thinkin of using some heavier duty shocks, any ideas is gratly appreciated.....thanks

20's? As in 20' tow straps? 20' hi-lift handle?

If you want power out of your WJ you really picked the wrong engine. The 4.0 is good at doing what it already does and not much more. To get a noticable power gain out of it you'll need to stroke it. Google for 4.6 or 4.7L stroker kits for it.

The weight of your wheels do affect your shocks, but VERY minorly compared to weight on top of the axle. I wouldn't get new shocks based on that. MX-6 are nice (adjustable), so are Bilstein shocks.

If you're looking at getting speed/performance/handeling out of your Jeep I suggest heading over to the Speed Freaks section at www.jeepsunlimited.com

20" wheels? Good lord. Seriously, you'll see a bigger performance jump by losing the crap pimp jewelry than you will with any mods to the 4.0 short of stroking it. The 4.0 is a basic truck engine, nothing more.

You might try edgeproducts.com , they dont list grands. But some of the parts will work they say.
Try streetjeeps.com they have some pavement pounders over there. Some v-8s with big numbers in HP.

http://www.wjjeeps.com/4sale/wj_for_sale.htm this is a link to kolaks email and some nice things said about him. He can hook you up with some engine mods.
