Anyone got some input on the best performance chip for the stock 3.8 engine? I am looking for something that is going to increase my HP but will still keep my fuel usage the same or increase it, thanks.

Hypertech is very good

Check out the Super Chips thread started by Jpop. A ton of info.

DO these programmer products (Superchips, etc) do anything to enhance the performance of bone stock 6-speeds?

I understand that with automatics and lifted vehicles, regeared with larger tires etc they are worth the money (optimise shift points on the auto and offer towing programs, re-calibrate speedo and adjust for gearing, etc) but for bone stock standard (manual) trans vehicles many have said they offer no benefit.

Anyone have any experience with them on completely stock (suspension, wheels/tires, intake, exhaust, etc) 6-speed transmission equipped JKs?

^^I am interested in that as well. I am eventually going to be getting a lift, tires, etc...is it worth spending the money on now, or should I just wait?

I asked this same question about the bone stock 6 speed. Even sent it to the Superchips rep that frequents the board....no reply, nothing. I guess the silence answered the question for me.

Would like to hear some feedback on this also.

I got the 6spd and the first thing I noticed was the delayed throttle response was GONE! You gain more power even on Tow or 87 Tune. The first issue I had was the very touchy throttle with the 6spd at slower speeds but Superchips updated this problem!

The second issue was on 87 tune after I updated the programmer was the knock/ping issue. After a while it was getting annoying and I believe superchips is still working on this issue based on individual people contacting them. I just switched to Tow mode on my programmer and found it worked just as good power/throttle response as the 87 tune minus the knock/ping.

My mileage went up with the programmer, gained a little more seat of the pants power, removed the delayed throttle, removed the (_!_) light when off-roading and I can program the tire size I am running. Also, the Crawl tune is awesome when off-roading!

A great investment IMHO!

A tuner will be my next modification. Superchips seems to be getting the most praise around here so i'll more than likely goto that. Hypertech is also something that i'm interested in though.

Even if I didn't get any more power I'd buy one solely for the fact that it gets rid of the throttle delay. It's been driving me nuts since day 1 but I just assumed that it's a feature of the fly-by-wire that I can't do anything about and have learned to live with it.

Can anyone else confirm that this is the case regarding the electronic throttle delay being eliminated by the Superchips (or any other) programmer?
