why would you want someone else to tune your car? better if you could get some numbers ie. rebound/compression damping, spring rates. anything that could help get you a better feel of the car. to your taste. not to the 'guy tuning your suspension'. best if you can try different setups and then decide on one that you like.
i'd suggest going to titans but they might not know how to 'tune' other brands besides theirs.
you could always give them a call anyway: 03-42979878 MPD Auto Centre
