25 bone stock 117 M8 tune done today. These numbers are with and with out factory air breather. Exact same tune. Could have gained a little more power with adjusting the e tune but had to put factory breather back on till new one comes in. Factory air breather is robbing 14hp and 9ft/tq. Highly recomend ditching factory breather and going with one that will breath before having bike dynoed.
