me and my friends have discussed geting my car tuned i bought it with a tune but as i upgrade my car i want to upgrade my tune. but i have no need to drive around at 24 psi all day and would like to get multiple tunes at say at 15,20,25 psi is their some sort of computer that can hold the tune in car so that all i have to do is press a button and turn my boost controller and be ready for the strip.and also whats a reasonable price for a professional tune thanks
