One of our recent customers drove all the way from Maine to bring us his E450 Coupe. Upon his request we completed a custom dyno ECU calibration and loaded his desired calibration maps onto a Dimsport hand held device. The Dimsport gives the user the freedom to switch between maps at their leisure. Needless to say the customer was very satisfied with the results and we’ve included his testimonial below.

“I was referred to WestTuned from another local tuning shop. Best decision I made. I reached out, had immediate communication, addressed all my questions and concerns and I decided to move forward.
Tune took about 4-5hrs (spent the day at Starbucks) they picked me up in my car, on the way back to the shop, the tech discussed with me what he did, what they found (nothing) and what I should expect going forward.
Got back to the shop and then showed me in detail how to use the hand held device. I wanted to have the option to flash back to stock if I wanted to.
After I left the shop I immediately noticed the difference in performance, very happy camper.
I would highly recommend WestTuned for any of your performance mods that you are looking to do.
I will be back!!!
Thank you!!”
