some bolt ons throw the cars AFR out of whack and as a result it'll drive like crap, I know with enough bolt ons this will cause such, and a tune will not only be "suggested" but it'll also be required also adding additional power.
Now to restate me question, I am unfamiliar with the VQ engines, and i don't know what their tendencies nor to what extent they begin to be picky. Will this IM and a set of HFCs require a tune right off the bat in order to function properly? IE car will drive normally, with a bit more oomph of course.
