Yes, you can run a smaller pulley (more boost) without a great deal of fear of damaging your motor, but while it only seems to go without saying for most, you will need to have your tune adjusted when doing so or engine damage can almost be a certainty depending on a few factors. If the tune that is currently in there is mild so to speak, you can likely add a pound or so and have it survive. However if it is not, even the smallest change may be too much. Irregardless, you will want (need) to get it retuned to get the most out of your new combination and to be for certain that it is still safe. I’m not trying to insult your intelligence, especially if you already were planning on having it retuned, but the idea seems to pop up from time to time, with a few people not realizing that they will need to make other adjustments when adding additional boost.
