skipm Posted October 16, 2009 Report Share Posted October 16, 2009 Has anyone put only a tune in their car? If so what are your thoughts before and after the tune, any rwhp numbers? I know a lot of the guys on here have put a pulley and tune on getting between 500-550 rwhp. My thoughts are upgrading the heat exchanger and doing a tune only. All I'm really after is improved throttle response and a moderate power increase. Had to park the car already the snow fell here over the weekend.
