I rode 132 miles last weekend in a local dual sport event. Paved roads, dirt roads, state trails and knarly trails (mud, rocks, roots, streams, steep climbs, etc.) Feels great throughout the power band in all conditions.
No problems with EXUP off (same result as 4 or 5 other folks with the same set up.) I did not change the ECU. The FMF "EFI Power Programmer" is back ordered for those that have tried to get one.
