Ay my boosted brothers Im thinking of installing Superspint headers. Now im running the stock Vf engineering tune but with these supersprints installed will i need a custom tune for maximum performance out of these headers or would they perform the same with the Vf tune? Allso would they be a problem with the Vf tune ? or can i just bolt them on and im good to go ?
