Ok, probably in a few weeks time I am going to be installing a procharger D-1SC, 60 lb injectors, and an SCT Big Air MAF. The closest person who can give me a custom tune is about a 1.5 hour drive away via interstate. How should I go about installing these components and then getting it tuned? Do you guys think that it will be driveable without any tuning once the new parts are hooked up, or should I try to get a tune on the chip beforehand? Thanks.
