Its a great mod,,, to empty your wallet...

You bought a 2.5 accept that and move on... Gear change will make the biggest jump in what you would feel as seat of pants power

^ this.

I've got the 2.5L. Have done injector upgrade, 4.0 TB and TB/intake bore, airraid intake, header and ultra flo exhaust components, e-fan conversion. It does assist in 'zippiness'. But seat of the pants? come on now.

I'm happy with where my 4banger is at right now in terms of drivability. It's actually zipping around on 31x10.5 tires and i upgraded my gearing to 4.10 (simply got new axles in there from the manual and an XJ D44 in the rear, as i have an auto which came 3.73 gearing).

You want lift, you want bigger tires - save your money and re-gear. (this will be happening next year for me). But beware - don't bother on the D35.
**EDIT**: also my jeep has never idled properly or ran properly on anything other than champion plugs and wires. The injectors an extra air allow me to widen the gap a bit.

Stop whining about the 'ride' - If your YJ ain't wrangling your soul free, then might I suggest you buy a stationwagon... at least you can fit all your bull**** in the back.
