Its been about a week since I finaly installed my a/f guage and I have been logging my A/f numbers. Sean's tune is Perfectly Stoich in at almost all rpms I did notice a quick dip to 13.5 At about 4400 but back to good. And his tuning was done based on a dyno run stock. This will be the fisrt dyno run for me since I Roe'd it need A/f numbers for my 10lb tune wish me luck:marchmellow: :burnout:
