tomkay Posted August 8, 2011 Report Share Posted August 8, 2011 Would a pulley change from 3.6250 to 3.500 require a new tune on 2008 with whipple s/c? Link to comment Share on other sites More sharing options...
jmn444 Posted August 8, 2011 Report Share Posted August 8, 2011 Is it intercooled? I went from 3.5 to 3.25 and it all was fine on the Dyno... Link to comment Share on other sites More sharing options...

jmn444 Posted August 8, 2011 Report Share Posted August 8, 2011 You could call whipple to confirm, but they told me I could go to a 3.125 on the stock frpp tune so you should be fine with that small of a change. Link to comment Share on other sites More sharing options...
