This beautiful GT350 came in for an MGW Short Throw Shifter installation.

The factory shifter in these cars is already good, but the MGW takes it to another level with:

* Crisp, positive gear engagement
* Shorter, more precise throws

Whether you’re carving back roads or making passes at the track, it’s one of the best upgrades you can make to a manual S550 Mustang.

If you’re looking for performance upgrades, repairs, or tuning for your Ford or GM V8, give Quick Shift Performance a call. We’d be happy to help get your hot rod performing its best.

2010 Roush Stage 3 Mustang GT

This Mustang came to us running poorly with very little power.

After diagnosing the vehicle, we found the dual Fuel Pump Driver Module (FPDM) wiring had been modified, causing improper fuel pressure and drivability issues.

Once the wiring was repaired, we discovered both catalytic converters had failed internally and become clogged, severely restricting exhaust flow. We replaced the damaged sections of the exhaust, refreshed the tune and got everything working the way it should.

The result :
✅ Smooth drivability
✅ Proper fuel pressure
✅ Restored performance

Whether your vehicle needs diagnostics, performance repairs, or tuning, we’re here to help.

Another one back on the road!

This 2010 Cadillac CTS-V is headed home after a complete transmission overhaul and custom tuning.

The customer brought the car to us after a previous transmission rebuild failed. The transmission would not shift into 4th, 5th, or 6th gear.

After removing and disassembling the transmission, we found the root cause—a broken 4-5-6 clutch drum.

✅ Installed a new billet 4-5-6 clutch drum
✅ Rebuilt the transmission with all new internal components
✅ Added an upgraded remote-mounted transmission cooler for improved reliability

While diagnosing the failure, we also found that the transmission tune was a major contributing factor. We completely revised the transmission tune and made several engine calibration improvements to optimize overall drivability and performance.

The results:
✔️ Smooth, crisp shifts through every gear
✔️ Significantly improved transmission cooling
✔️ Better engine performance with a horsepower gain from the revised tune

If you’re experiencing transmission issues, performance concerns, or need custom tuning, give us a call.

C3 Corvette that we wrapped up last week.

The customer brought the car to us with complaints of a poor running condition. After diagnosing the issue, we determined the original points distributor was failing. The owner opted to upgrade to a modern HEI distributor conversion.

During disassembly, we also found improperly gapped spark plugs, burnt plug wires, and a non-functioning vacuum advance.

We installed the new HEI distributor, MSD plug wires, and fresh spark plugs, eliminating the drivability issues and bringing this classic back to life.

This Corvette is all squared away and ready for many more miles.
