Well I am sure to get lambasted for even uttering such a stupid question but here it goes. Currently running a 2010 Sport, 3.73 auto. I really want to skip 33s and go straight for 35s but obviously I am not a millionaire and can't do all the associated mods at once. I am worried about gas milage going into the basement until I can re-gear, as it's my DD. I understand its a jeep and a brick and a big box but it would be stupid to get 10mpg as it would cost a ridiculous amout to run. What are the pros and cons of each of the programmers (ie power increase and milage retention) in respect to 35s on stock everything?

 

You won't get lambasted for asking a question. (though you might for asking the same question that has been asked about 10 times in the last two days...)

You lose performance and mpg's by going to bigger tires. No way around that. You can regain 'some' with a tuner, and you'll regain 'more' with new gears. You need both to get you back to stock-like performance.

Manuals will see less of a negative effect than auto's

A Programmer will only set the new gears and tire height. (AEV ProCal)

A Tuner has performance settings also. (Superchips, Hypertec, Diablo)
There are a few thousand Superchips posts on this site for you to look through. Not nearly as many on the other two, but a search will find you some...)

 

First thing if you are going this route without doing gears just keep the OD off. Don't be tricked, just keep it off.

As for programmers, the Superchips has a huge following and some new transmission options not elsewhere in the market. If you are looking at some upgrades beyond the typical bolt ons, DiabloSport, but also know you will need to pay for custom tunes to support them.

 

i got a 2010, two door, with 35's stock 373's, superchips, cai, exhaust, getting around 11-12 on a good day.

 

I know there are lots of posts on the flashpaq, I do appreciate the input. Any alternatives to it tho? Jones had a large following too, before everyone drank the kool- aid that is.

 

Buy a Jet stage II or a Hypertech. They don't have a large following and aren't serving up Kool Aid.

 

 

I am in no way saying it doesn't work. Just wondering if anyone has used a few different ones and had better results. I can't imagine too many of the superchips ppl have dropped the cash to test it against the others.

 

I had a Hypertech and sold it after I received my Superchips Flashpaq. The guy I sold it to also parted with it and bought a Flashpaq. It's been beat to death as far as a topic goes here and the only real rival has been the DiabloSport Predator.
