J & J Complete Tuning LLC

J&J complete tuning came all the way to my town from the coast to hattiesburg to put a tune on my 2013 toyota tacoma. I was a little nervous about it and for being a 2nd Gen I didn't thing it would ever be right on a 6in left and 22x10 wheels and 35's tires I taught I have messed up by doing that to that old of a truck didn't want to shift right lost a lot of power and just taught I have messed up. He showed up made me feel confident in a man that I never meet to to plug his computer into my truck and made my truck come alive again. Now she pushes them 22x9 wheel and 35's tires like im back on stocks with alot of power on top of that these tunes dont just help the proformance of the truck it helps with what ever set up in shifting the sluggish gas pedal and give you hp and torque if I woul

John put a mcb elite+ tune in my 2019 TRD Sport, and boy did my truck come alive. Runs like it should. Smooth shifts and great throttle response. Thank you!

Great to work with, love the kdmax tune installed on my truck. No more gear hunting which was my main concern. J&J were easy to work with, local to the MS Gulfcoast which is great in the event you would like to have the tune adjusted to fit your needs. I look forward to future interactions with them.

had the tune done and it's a totally different truck Best thing I could have done to it. I highly recommend it.

John was a great help. Very informative and super friendly. Don’t hesitate to use him for your truck tuning needs. The KD Max tune made a big improvement to my Tacoma and I couldn’t be more pleased.
