Is tuning safe for my engine?

On a healthy engine with the right fuel, yes. We check the car over first, so the tune goes on a car that's ready for it.

Will my car still pass smog?

It depends on the car and what's fitted. We'll tell you where your car stands before we start, and we don't do emissions deletes.

Can you inspect a car before I buy it?

Yes. Bring it in, or have the seller bring it, and we'll go over it and tell you what we find before you buy.

The questions people ask us first.

Text us your car, what it's doing or what you want done, and a photo if it helps. We'll come back with a price, and nothing gets worked on until you've approved it.

BMW is our speciality, and we work on Mercedes, Porsche, Audi, Volkswagen, MINI and Land Rover as well. Driving something else? Ask us.

It depends on the job and on parts. You'll get a timeline with the price, before any work starts.

If it's on and steady, it's usually fine to drive in, but don't leave it long. If it's flashing, stop driving and call us. That usually means a misfire that can damage the engine.

No. In the US you can have your car serviced at an independent shop without voiding a new-car warranty. Keep your service records.

It can affect claims on the parts a tune touches, like the engine and transmission. It doesn't void the whole car's warranty. Ask us about your car's coverage before we tune it.
