That is correct, if you pull the baffles and put the Thunder Torque Inserts™ in you do NOT need to tune/reflash. The M8's do not have the lean problem the Twin Cams do. Of course, any M8 will run stronger/better with a good tune, even if it is bone stock, but no damage to the engine if you don't.

Here is a LINK to a report on the M8 engines, part of which shows the AFR and the ability of the ECM to adjust to varying conditions.
