Curly and the crew hooked me up right quick! I called in the afternoon to get a Revo tune on my Mk7 GTI and they had me out the door that evening. Had a great time chatting with the Griffin team while I was waiting and learned a lot about what I can do for my GTI in the future. Thanks for the great service, knowledge, and results!

Curley did an excellent job with my 2004 Isuzu. He found the problem and fixed the issue to my complete satisfaction .

Brought my SQ5 in for an MTM Cantronic tune, and waited for the vehicle to be done. Was able to browse through a wonderful collection of automobile related magazines while waiting, very comfortably in a social distanced environment. As for the tune, I may be jaded with the additional HP afforded by the tune, or perhaps was expecting more. That being said, the additional HP is definitely there, and is delivered in a seamless manner. The car behaves just as one would expect, no glitches, stumbles or odd behavior. It is as if it was provided by an OEM tune, nothing changed, with the exception of additional HP. Would highly recommend the MTM Cantronic, it looks fabulous in the engine bay and delivers on what it promises. As an additional benefit, MPG is up by about 1 MPG over the past 3,000 miles, so I expect the additional economy will continue. The staff at Griffin, from Terry on down, is nothing short of spectacular, they know their products, know the cars, and care whether you're in for routine maintenance, or a no holds barred upgrade, they can get it done. I've been dealing with Terry and staff for well over 30 years, and some things don't change, the passion for the cars, the professional manner in which the customer is handled, and most of all, the immense knowledge of Terry and his staff. Would recommend to anyone looking for either performance upgrades, or a viable alternative to having to go to the dealer.

Griffin Motorwerke ar so professional and now I'm a customer for life. Griffin did a splendid job upgrading my Macan GTS with a Cobb Stage 3 Power Package. Not only was the install done perfectly, they also fixed an inherent problem with the Macan aluminum valve cover bolts which shear off at high torque demands. They replaced the aluminum bolts with stainless steel ones. Problem eliminated. The Porsche Macan now has a deeper voice, snarls on startup and growls when prowling down the street. My neighbors love it too! She's peppier, responds quicker and is just overall a very different drive experience. Thanks to all the folks at Griffin - great job!

Griffin Motorwerke installed Mountain Pass Performance Comfort Adjustable Coilovers for us. They communicated well and made it convenient to drop off and pick up our Model Y, which could have been a pain because we live a few hours away. The coilovers made a huge difference and Griffin dialed everything in nicely for us. Ripping back up 80 into the mountains was a joy and the suspension tightens up well at speed while dampening the vibrations coming off rugged California road surfaces much better than the stock suspension. I highly recommend working with Griffin for all your Tesla upgrade needs!

I always receive fast professional service at Griffin.. Curly and Nate et al have the shop running smoothly and following perfect COVID protocols. When I brought my car in it was running so poorly I had already started shopping for a new car... I left with my car the very next day it was running like it’s new!! Thanks guys! I’ve already told all of my friends about the service at Griffin, now they will hear it again..
