Jeff's Tuning and Performance

Max McGillicuddy

If you are looking for tuning, especially for GM products, this is a great place to go. Had some tuning done on my 2010 Avalanche. Jeff had it done in no time flat and was extremely knowledgeable!

Jeff made sure the tune was right on my Trailblazer SS with the 6.0L LS2 after I installed a Cam, Headers, etc and that I was happy with the tune. I'll be back after the Nitrous is installed.

Very knowledgeable owner. Going to have him tune my baby with a little more work. Problem child should be nice after this. Update: I couldn't be happier. My 13 Camaro SS was a problem child, not any more. Jeff figured it out and I couldn't be happier with his and his teams work. The car pulls like a freight train and doesn't feel like it fights itself anymore. Power all over the place and mpg is crazy compared to what it was before. Good job sir. You have my buisness. I will be back with the next one.

Called Jeff to see if he could do an ECU flash for a 6.0 LS3 with an aftermarket camshaft. He said, yes bring the ECU over and I will have it done in 20 min. Brought the ECU there gave him the cam specs, and done. Then brought the truck for final setup and just as expected, superb quality service. My customer and I were happy. To you folks out there, I will recommend him any time of the day. Jeff, thanks for taking care of my customer and I.
