Superchip advice for JK

Hey guys, since I can't afford to regear right now I'm thinking about getting a superchip. Is it worth it? I have a 6cyl. 09 JK 3.21 standard with 33s. I don't do offroading. Thanks for all the advice.

You'll need a programmer anyways to correct your speedo. Cheapest option is Procal, but it doesn't offer any performance gains. The Flashpaq does give some performance boost, but nothing like gearing. Also, most people say it's more beneficial for automatic JKs. Another option (the priciest) is the DiabloSport tuner.

It's similar to the Flahpaq but it also allows you to do custom tuning. I don't know if any of these options are going to give you enough improvement to cure the sluggish response of 33s on 3.21 gearing but good luck.

For JKs, I've seen some of the guys running RIPP systems using the DiabloSport. Most people use the Flashpaq (including myself) because it's cheaper and has been around for a couple of years before DS came out with a JK option. If I hadn't already purchased mine, I would be considering the DS or curiously waiting for more information on the Superchips VIVID.

To be honest I don't think a Superchips is going to do much for you, especially with your manual transmission.

Night and day difference after running the Superchips! It's like a whole new engine. With that said I have a 2007 auto with 4.1 gears running BFG All Terrain 285/65/18 (33's which actually measure a bit less).

If I had to do it all over again I would have purchased the Superchips years ago.......

Flashpaq will not solve a gearing issue. If your 3.21's are the problem, increase of HP is not your solution. You still need to get the HP to the rear wheels. Gears are you real answer. Find some 4.10's out of someones 07.

I have a manual trans Rubicon. I still have stock 32" tires and a lift. I went ahead and got the Flaspaq as I got a really good deal from 4wheel parts. I have tried most of the tunes including the 87, 91 and 93 as well as the "mileage" tune. With the 93 and 91 tunes I noticed a power improvement across the RPM range. While it's certainly NOT an OMG change it does help.

Can someone plz tell me if the superchip programmer #3875 will work on the 2.5l??? superchips says just gas dodge/jeep. it doesnt specify engines and other sites that sell superchip say dodge/jeep 3.9,4.0,5.2,5.7,5.9 etc. but no 2.5l? if it fits all those other engines it cant be made for one vehicle and engine. I once tried a jet chip from a 5.2 ram in my 2.5 and it work fine with no issues but i didnt see where it improved my truck much so i would really like someones help and advice on this, thanks in advance.

Day and night difference on mine as well. I'd certainly buy a Superchips again

I tuned my 09 JK 2dr 6spd with Superchips. I experienced a very noticeable improvement in accelerator pedal response. The SC software modifies the electronic throttle circuit, giving greater throttle opening under the hood for a given amount of tip-in pedal input. It's a nice, brisk improvement for driving around town.

The power curve increase on any of the SC tunes is harder to discern, but the engine does rev more freely and has a seat-of-the-pants power increase above 3,500 rpm. Not huge, but it's there. I use the 89 tune with 89 octane fuel. I can easily get away with 87 octane around town, but I have occasionally noticed some light "flutter ping" when agressively going up through the gears. My gas mileage did not change in either direction - basically always 15.0-15.5 mpg around town.

You notice the impact of the SC tune most when you go back to the stock tune to visit the dealership. You find that you can't wait to get back home to reload the SC tune of choice.

Also, there are NO long-term damages to your engine, unless of course that a SuperChip tune gives you the urge to drive like an idiot.... and you aren't aware of what engine pinging sounds like.

FWIW: I would get another SC Tuner with out hesitation. I also try to use the recommended grade of fuel, or just take it easier until gas prices drop a bit.

My Superchip was ok but much better than most of the other tuners out there but I wouls challenge you to try a Diablosport tuner they give a 30 day money back guarantee for satisfaction and many dealers even will allow you to try it before you buy it.

Having both I can honestly say the Diablo opens the enigine up even a little more with even smoother shift points and a few more features.

I beleive the Predator runs on avg about $30 more then the Superchip and the Trinity which yes is expensive but will give you custom guages is around $599 most places but when you consider it is a superchip, guage pod, and sprint booster in one you are saving money in the long run.

Why doesnt it fit the 2.5l? i thought all OBD II were the same? I mean im just trying to understand why if you can use them on the 6 and 8 cylinder why not the 4 cylinder? If it can change both the 4.0 and the 5.2l it is NOT a specific tune for ONE vehicle sooo it sounds like it mainly just advances timiing a lil and when it takes away TQ management and firms up shift ppl FEEL a power increases. I know ppl who have used models that claim there only for 04 and up on there 02 and ppl who have used programmers for diesels on there gas engines. Sounds like there no major tuning going on. Sounds more like a lil advance in timing and removal of some things which is where ppl feel the "gain". Can someone explain to if and why it would not work on the 2.5l? I know what engines they claim it works with but that means nothing.
