I'm not sure what you're asking. You're wanting a full custom tune which includes your new mass air meter or you're wanting a stock tune with just the mass air meter calibration included? And you want the tune to be loaded on to a chip you already have?
As long as you have the new style chip (small green) then we can do this but I'll need some information from you. I'll need to know what the short term fuel trims are with your vehicle (with the new MAF installed). The cost for this would be $100 plus shipping. If you have the old style chip (black L-shaped) then you would need to purchase a new chip too ($239).
