Yes, you can do the pre dyno inspection yourself. We are Certified Cobb Pro Tuner, so we can also provide the inspection for a $300.00 fee. This fee includes a compression check and leak down. Inspection of all fluids, shocks, struts, bushings, tires, brakes, fuel system, smoke test, air intake system, and exhaust system is also done with the pre-dyno inspection. If you are doing the inspection yourself, please ensure that it is done thoroughly as once your vehicle gets onto our dyno, and we decide, for whatever reason, we have to take off the dyno, you will lose your deposit. You may also download our ” Dyno Test Checklist” for your convenience.
