I have had two of the bigger, most well known shops tune my car. Neither of them could really figure out how to tune the automatic. With both of them it always was in to high of a gear, and had that hesitation when you wanted it to downshift.

Well that was until I had Monty at JMS Chip tune my car. Now the trans is always in the right gear, it doesn't shift into 6th till 60mph. If your on the highway, just a light tap of the gas pedal and it downshifts into 5th with almost no hesitation

I also have a circle D converter which also exaggerates the hesitation, so if he can get it right on my car, I am sure he can get it right on your car

tell him Don from Boston referred you
