JIMTUNE DIAGNOSTICS

Diagnostics are just something few are good at in the auto and truck repair business.  Here at JIMTUNE, this is just everyday work, and for well over 30 years, have been the last stop for many people in the pursuit of a correct diagnosis. A correct diagnosis will save you a lot of money, and no matter what your income level, your money was hard-earned and wasting it on an incorrect diagnosis is just unacceptable.  So, whether it's engine, transmission, HVAC, or any other system in your vehicle, on most makes and models,  JIMTUNE will save you money and time from the start.


--Schedule your Diagnostic Appointment Today !

 

+   As a courtesy, we offer FREE CHECK ENGINE LIGHT code reading. Keep in mind that this is not considered a diagnosis, but what checking the codes does is give you some idea of where the problem may be, and whether or not the problem needs to be dealt with immediately, versus whether it can wait.

Jim, I just wanted to update you on my car since the tune. As for fuel mileage props to ya on that one Im doing better than I was stock. I drove the car from Stillwater to Coffeyville then to work everyday for a week with some added stuff inthe evening when I took some of the interns for a ride. So I would say spirited driving with 3 or 4 runs to 100 and a big burnout. For that tank I got 18.3mpg. Then I checked it once driving from Coffeyville to Stillwater not driving easy by any means and running mostly 75 and 80 and got 23 mpg. Then had a week of mixed highway and in town without much full throttle but still driving the car pretty decent and got 21.8. So great mileage and thanks again.

Hey Jim, I just wanted to say Thank You for all the work you've done on the Mustang! It's an amazing change from the canned tune that was on there when I bought it. You're suggestions on basic improvements to the ProCharger setup and upfront explanation of costs made this a great experience. The car runs amazing, and I sincerely appreciate your standing behind your work and re-tweaking the tune. The car is great on a daily commute, and a beast when I get on it. Much more linear and smooth through the pulls. It's been 10 years since I had a "Mechanic", someone I could call if I had questions and who is also able and willing to tackle anything I throw at them. It's not easy to find a shop or person like that anymore, but you are the man! Can't wait to get this thing on a Dyno and see what numbers it's putting down this summer. Given my addiction for reliable power, I'm sure we will have plenty of projects in the future.
