Rolling Road check list plus terms and conditions    
         
 

Treat a rolling road appointment as if you were taking the car for a MOT or to the race track , Silly things can really slow the job down which in turn could cost you more money.

Pre-Dyno Checklist
DO NOT bring a car with low or no oil pressure.
DO NOT bring a car with excessive mechanical noise.
DO NOT bring a car with any engine check lights on, I will not put it on the dyno.
Is the car leaking oil excessively ,small drips are fine.
At least half a tank of fuel.
Check the throttle cable and linkage, are you getting full throttle?
Check the tires for splits or damage, no remoulds allowed.
Check all wheel nuts, cars with loose or missing wheel nuts slows the job down.
Is the timing belt installed properly?
Have you pressure tested the intake system to check for boost/vacuum leaks?
Are the plugs new, proper heat range, and gapped properly?
Are there any exhaust leaks?
Is the cooling system in good condition?
Are the plug wires new?
Is the fuel system adequate (pump size, injector size, fuel line/filter)?
How long ago was the fuel filter replaced?
Is your boost controller holding steady boost?
Is the motor in good mechanical condition, what is the compression?
I suggest you complete a compression test prior to your tuning appointment. Typical compression test results should be as follows:
8:1-8.5:1 compression: 150-170 psi per cylinder
8.5:1~9.5:1 compression: 170-210 psi per cylinder
9.5:1~11:1 compression: 210-275 psi per cylinder
11:1+ compression: 250+ per cylinder (highly depends on cams being used)
