My son in law is putting short shots on his fxdb. do we need to modify the af ratio? we plan on an intake mod. later and then install a TFI. I was hoping he could run it for awhile with just the exhaust change, hoping that the ECU could adjust enough till we could get the TFI and the K&N intake. Any opinions?
Thanks,
Harley
