I pick up my 09 4dr on monday and was wondering how long I should wait before buying a flashpac, I don't want to disturb the pcm break in procedure. Has anyone tuned a brand new rig or should I wait a couple thousand miles.

 

I tuned mine week two.

 

I put mine on with about 4000 miles...

I don't see any reason why you couldn't put it on after about 500 miles or so. I wouldn't do any less than that for standard engine break-in procedures.

What does the manual recommend for break-in?

 

Anyone else, I'm itching to order one

 

I put mine on after 600 miles(two round trips to work). Best thing I could have done. Made it drivable in the city, at least I feel that it did

I still average 21 mpg, and just got back from a round trip to Kerrville, TX, (the hill country for me) and averaged 20.9mpg driving 65 to 75. I was not driving for milage so was surprised to total it up after I got home.

 

We have done a few with less than 2000 miles no problems.

Also we have a ton of them in stock and ship the same day!

I just installed mine at 1,000 miles.

 

Will this tuner burn out your engine?

 

I had one on my Mustang GT and loved it. I will be getting one for my JK real soon
