A true BMW classic back in the shop. 🔧

This BMW 840Ci came in for valve cover service, a new pinion seal, and scheduled maintenance to keep this V8 grand tourer running as smoothly as the day it left the factory.

Keeping legends on the road, one service at a time. 🚗💨

Another clean upgrade in the books. 🔥

This Supra stopped by for an intake, charge pipe, and inlet install to help it breathe better and unlock more performance. The turbo sounds are definitely worth it. 🚀

What mod should be next?

This 992 Turbo S came to us after being tuned elsewhere and struggling with limp mode issues while falling short of the power expected from a setup with Pure Turbos and an iPE exhaust.
We upgraded the car with a do88 intake & intercooler piping, IPD plenum, custom methanol kit, and dialed everything in with our in-house ECC ECU/TCU software. After custom dyno tuning on 93 octane, the car put down 850WHP 652WTQ and now performs the way it should. 🔥

This Mercedes SLC43 came in for a full dyno tune session and the results speak for themselves 📈🔥

Baseline numbers came in at 368WHP / 391WTQ
After tuning: 400WHP / 475WTQ
