I heard running our jeeps with the front wheel drive disconnected it really bad for them. Is this true? I was going to get a pull once I get my cai on and then another after I do an exhaust but the only place to dyno it close is not set up for AWD. Will this mess my stuff up?

Its a good possibility.

I know quite a few here have done it due to not having access to an awd Dyno.

It would be my guess that for a couple pulls it might be ok but long term 2wd use could do some damage.

Try checking around a little harder, check if you have any Evo or Suby tuners around.

I am curious about this as well.....Is it just a fuse pull, or do you need to do more than that (IE: Disconnect the front drive shaft/transfer case)?

it just a fuse abs and ediff fuse
