About Us

At Church Automotive Testing, our policy is simple - customer satisfaction

Satisfaction Guarantee

Your satisfaction is important to us, now and in the future.  When you visit Church Automotive Testing for tuning, our job has just begun.  If, for any reason, you're not happy with your results, feel free to come back and we'll do everything we can to fix it - for free.

Please understand that this does not mean we'll be able to work miracles - the amount of horsepower your engine produces is a product of the parts you've chosen, the health of your engine and the need to make sure your engine runs safely and reliably. 

Payment Policies

At Church Automotive Testing, we now accept credit cards. Visa/MasterCard/Discover are welcome.Cash payment is still available as well.  Returning customers may pay by check.  Business clients may be eligible for invoice billing.

Other Things You Should Know...
- We reserve the right to refuse service to anyone.  Serious engine problems and missed appointments are cause for refusal of service.
- Wheel Locks - the Dynapack requires that we remove your drive wheels for testing.  You must bring your wheel lock key with you!!
- Fuel - make sure your car has at least a quarter tank of fuel when you arrive to ensure that we don't run out on the dyno.
