I have an XB9s With Pro package and XB12S headers. I get some backfire and carb farts at time and I don't seem to have to power range until 4,000 to 5,000 RPM range. I had bought the bike used and have been thinking of getting Directlink to tune the bike with, however I don't have access to a dyno. Can I tune this bike with JUST a wide ban O2 senser setup and directlink Properly?
