im going to install an intercooled V2 vortech. I have a Pro M 80mm, and the chance to pick up a set of 39lb injectors for $100. should I do this and have my maf calibrated with the 39s (with the dynotune), or spend the extra money to get 42s and a lightning 90mm? I dont plan on makeing any more power than just the basic SC install any time soon.
