If the tune-up fails by a little, then you will need to run a about 3/4 tank of Super 91 to 93 octane. That's just on the fuel side. On the air intake, if the shop doesn't open the air-filter housing, take the air filter out just before the testing and place back after. Most of the time shops will not open that up on a van.
