What are you even talking about? I felt it was more beneficiary to run more timing instead of pulley

Depends on the setup, may even differ car to car some. Look at it this way, you went from a rather inefficient setup =gen3+heat to a more efficient =genV+vanilla ice setup. Timing will give you some power, but when on a stock cam, you bought yourself some room to run more boost safely. You can run a leaner a/f with that intercooler, near 12's makes some good power but if you dont have a wideband I wouldn't get to lean happy. This also helps when running a 3.2" pulley or smaller on stock injectors, since they should be on the verge of maxing out (100k+ fuel systems vary). I would run a 3.2" on stock timing, lean out the afr a tad and then start bumping up timing. Should feel the difference on the butt-dyno, probably even at stock timing. Keep in mind the temperature and weather when tuning.
