Why A JB4?

Okay I've seen multiple owners on this forum run the JB4, can someone answer why this software? Is it because it's more affordable? Better results? The autotune self feature or what?

Essentially, it is a piggyback tune that you attach to the car's ECU.

You can find all your answers through GOOGLE or the search....

JB4 packs such a big punch for its price. The features it has, along with the power it provides makes it such a great product.

the fact that you can use meth/e85/race gas by just pressing a couple buttons is crazy(it takes seconds, not minutes like flashing a car with cobb)

Its a tune that you can actually use and is integrated into the cars system. You can turn your fuel gauge into a boost gauge, read your air/fuel ratio/ and much more. It has many safety features very beneficial for tuned cars. Plus the autotune feature. To many good things to list about the jb4

Procede can also do almost everything jb4 can do and is also a great tune.

Awesome thanks, been researching and using google but still wanted to ask those who've dealt with the tuning system themselves..

What is this a dating thread? If you guys want to hit on Sara leave her a vistor message..

@ Sara504 thanks for a different opinion, why the COBB? I doubt breaking a nail is the reason you didn't stick with the JB4

I'm also curious why JB4 over Proceed? Looking to get a tuning solution too.

I'd most likely go with JB4 because it's cheaper than cobb and you can also change maps on the fly with the steering wheel but one thing that makes me want COBB is because it's really easy to install and won't require going in and out of the ecu just to take out the tune for dealer visits.
