Prior to your tuning appointment, please review our Pre-Tune Checklist to make sure your car is ready to go on the dyno.

Verocious Motorsports Pre-Tune Checklist

When you arrive for your tuning appointment, we will do a preliminary check of your vehicle prior to strapping it to the dyno. However, there are some things you can check yourself prior to your appointment to make sure your car is ready and in tunable condition.

To help your tuning appointment go as smoothly as possible, and to help you avoid any unnecessary expense, please review our Pre-Tune checklist and make sure you have addressed as many of the items as possible. We are, of course, here to help, so if there is anything you come across that you are unsure of, or were not able to check prior to your appointment please let us know so we may double check it prior to tuning your car.

  1. Tuning is not a problem solver in most cases. Aside from larger injectors and larger MAF housing diameters most components can be installed without a major adverse effect on drivability. If you are having drivability problems please bring it to our attention, so we can advise you as to whether a tune will fix your problem, or if further diagnostics need to be performed.
  2. Make sure you have a relatively fresh oil change, within approximately 1,000 miles
  3. Check oil level. Bring an extra quart with you in case we need to top off the level.
  4. If your car has over 50,000 miles replace your fuel filter.
  5. Make sure you have a clean air filter. If you use an oiled air filter, make sure the filter is not over oiled.
  6. Install a fresh set of spark plugs gapped to no more than .032” for boosted applications
  7. Make sure you car is not leaking any fluids. If your car leaks fluids on the dyno, you will be charged a cleanup fee.
  8. Check for pre-turbo exhaust leaks, as this will affect turbo performance.
  9. Check that all intercooler piping connections are secure.
  10. Check vacuum/boost lines, make sure they are secure, as short as possible, and do not have any changes in diameter.
  11. Tires should be in good shape, no belts showing etc. There should be no more than a 4/32” difference in tread depth between drive wheels.
  12. Check tire pressures, to make sure there is no more than 2 psi difference between tires.
  13. For AWD and RWD vehicles, make sure the driveshaft and carrier bearings are ok.
  14. If your car has excessively low or large bumpers, spoilers, splitters, or under body panels that may interfere with loading your vehicle onto or securing your vehicle to the dyno please remove them.
  15. Please make sure the car is filled with the fuel for which you want your map built. Do not use any fuel additives unless you plan on using them all the time.
  16. If you would like a pump gas tune, but have used race gas recently, make sure you have run at least two tanks of pump gas through your vehicle as this will ensure most of the race gas will be out of the tank.
  17. If you would like a race gas tune we can recommend and supply the fuel. However, make sure to check your local race gas availability, as the tune will be fuel specific. If you are tuned on Power Mist TO-137, VP C-16 will not run properly in your vehicle, or visa versa.
  18. Make sure your suspension and brake combination are suitable for your wheel horsepower numbers.

During our preliminary check of your vehicle, if we find issues that need to be addressed we will bring it to your attention. At that time, you can decide to have us fix the issues, which would be subject to our hourly labor rate. If you do not want us to fix the problem areas, and would rather fix them yourself, we will have no choice but to reschedule your appointment. Of course the latter of those options is not ideal for you or for us, which is why we have developed this checklist as a guide to see if your car is ready for tuning.

Please feel free to contact us with questions.

Thanks,

The Verocious Team
