Performance Upgrades & Tuning

More power, more grip, more grin.

Sometimes the bones are good and you just want more. More throttle response, more midrange punch, more confidence when the light goes green. Our performance department turns a stock cruiser into something that pulls hard and sounds even better doing it.

We build performance as a balanced package — power, fuelling, ignition, cooling and driveline working together — so the upgrades feel factory-engineered rather than bolted on.

Performance done as a system

Adding a big carburettor without addressing fuel delivery, or a cam without matching the converter, just creates new problems. We plan upgrades around your goals and the car as a whole, so every dollar adds real, usable performance.

  • Carburettor rebuilds and EFI conversions
  • Supercharger and turbo forced-induction
  • Headers, exhaust and induction upgrades
  • Camshaft and valvetrain packages
  • Ignition and engine-management tuning
  • Cooling, fuel system and driveline support

Street manners intact

A fast car that overheats in traffic or fouls plugs at idle is no fun to own. We tune for a broad, tractable powerband that behaves on the street and delivers when you open it up — verified on the dyno, not by ear.

Quality installation with the supporting mods done right.

04

Tune

Dyno tuning for power, safety and everyday drivability.

Common Questions

Will more power hurt reliability?

Not if it is done properly. We build in the supporting fuelling, cooling and driveline so the extra power is sustainable, not fragile.

Carb or EFI?

Carbs suit a period look and simplicity; modern EFI gives better cold starts, economy and tunability. We fit both and will advise for your use.

Can you make it pass emissions?

Where road compliance applies, we tailor the package to stay legal in your jurisdiction. Tell us your requirements up front.
