Thread: wbody store full-size intercooler with 42.5's = what size pulley?

An overkill tune is the mid point between an off the shelf tune, and an in-car tune.

With that level of modification, you'll need to be tuning it specifically for the car, to get the most potential.

An overkill retune would be a good starting point if you dont have a tuner immediatley available.

If I drop to only a 3.2, could I retain my stock injectors? However, wouldn't running a 3.2 with a full size IC be almost the same power wise as my current 3.4 setup? I feel like I should be at a 3.1 or 3.0 with an IC.
