[QUOTE="The Beast 2014, post: 15310684, member: 176558"] Ok, dumb question but maybe you can help. My tuner is swamped so I don't want to harass him as we are all getting ready for an event next weekend. Currently I am running a 3.25 inch pulley on about 6.5lb of boost. Can I pulley down to a 3 inch without a new tune? I know I will get more benefit from the new tune but if I can't get into my tuner for a bit I was curious if there are any benefits? My fuel system is ID1000's with a BAP so I think I have the room. Plus with these cars I thought the computer will make adjustments from timing if you are running short on fuel. Thoughts? [/QUOTE]
