Tuning does not fix mechanical issues or misfires. Tuning is designed for vehicles that are already in good running condition and designed to make aftermarket parts work properly together.
If you feel your car has any mechanical issues or is misfiring please contact us and we can schedule a time before your dyno tune and fix any problems it has. If we strap the car on the dyno and find misfires or other issues we will charge you the dyno rate of 150 dollars a hour to repair the issues or remove the car from the dyno and re schedule your tune and charge you for the time on the dyno.
We do offer pre-tune inspections. (Call for vehicle pricing). Our pre-tune inspections can include:
There is nothing worse then getting your car tuned and not make the power you were hoping for all because the fuel pump or injectors you just purchased are too small or you end up with massive turbo lag because the turbo you choose is to large for the power you want.
Feel free to contact us and we can help guide you through picking all the parts for your build. We do this all day everyday and have a lot of experience with aftermarket parts and can help you decide what turbo, injectors, fuel pump and many other parts to get the most out of your tune and have a great driving car for the purpose you plan to use it for. We also are parts vendors for pretty much every major performance parts brand out there and price match any listed price online.
Contact us for your build advice, parts purchases, and part installations.
Tune appointments will only be held for up to 30 minutes past the prior scheduled time. At that point we will move on to the next appointment and you will have to reschedule your tune for a later date and pay another deposit fee.
The $50 tune deposit goes towards your tune time slot. This deposit is non-refundable and non-transferable. If you do not show up, show up more than 30 minutes late, cancel your tune, or reschedule your tune date and time then you forfeit that deposit. You will then have to pay a new $50 deposit to schedule your new appointment.
