Hey guys I live in Massachusetts and was going to get 4.10's done very soon. Leonards Performance does 4.10's for $550 for Parts and labor and Dez Racing does the labor for $300 so probally about the same. Does anyone have any recomendations? I want to go to the better shop. Thanks guys - Shaun

i own a shop in B.water mass,from what ive heard leonards is not the best people to have work on your stang....i personally fixed things they messed up more than once....customers said a sixteen year old kid was working on his stang at leonards... ive heard dez racing has a dyno and are good at tuning cars....have you heard of MPE racing in whitman ma all they do is mustangs check out their website youll be in love
I just got my gears done yesterday at Dez...GO THERE!!! The man is simply amazing at installing gears and knows everything there is to know about mustangs. He is honest and I will be going back to him for the rest of my performance mods. His shop is a bit of a drive for me, but its well worth it for his honest deals, excellent quality of installation and attention to detail. I was recommended to him from 3 of my friends, they all got there cars worked on by him and they have nothing but great things to say. You can't go wrong!

Yes, Mike Dez does dyno tuning. They also do anything, from gear changes, to engine rebuilds. Dez Racing, does everything from A - Z. Dez does the tuning, while Brian does most of the mechanical work. He has done, a lot of work for me in the past and I have never had any complaints. Being disabled, Brian does most of my mechanical work that I can't handle anymore. Dez, did most of my tuning now I handle that part myself, but still use Mike's dyno to get my air/fuel mixture right, Mike D. P.S. They do excellent work, and you'll see them in Muscle Mustangs and Fast Fords on some of their projects, or product reviews dyno proven.
