I would let you use my program, but its a maftuner. Sorry. That calibrator hasn't been around for very long, so problay no one on here will have one. Like stated before it $100 to re-tune through them. But if you have friend with a maf tuner, you could always plug your maf, into his car/tuner, and attempt to make some adjustment that you think would suite your car better, than switch it back. I never tried but it may work.
