Local dealer has a tune-up special, so I think I'll take my 280Z in to get the WORKS. I would like to get printouts for all the calibrations or measurements they do while doing the tune-up. What, if anything, can I get or request to get? I think it would be nice to see specs on air-flow, fuel-flow, and other stuff relative to engine perfomance. I could use it as a baseline for (engine mods.)
Also, I keep all the service invoices, printouts (diagrams, etc) that I can to document the car, or for my own records. That way you can show it to a buyer, if I ever sell it, and it should help you get a better selling price. They do it on collector cars.
Also think I will get the engine bay/undercarriage steam cleaned while there.
