Im hoping to pick up my first 99 Buell S3T here shortly. I just wanted ask if a EMC/FI upgrade is a must after adding a V&H muff only.
Thanks Guys.

The fuel injection will be OK with just the Vance&Hines upgrade.

Spend the money for a race ECM. It will be like a new bike.

Not sure if the S3 and X1 share the same ECM or fuel maps but my X1 did occasionally backfire even with just a V&H slip-on (SS2R). I ended up changing the stock maps with race maps via ECMSPY and the bike is so much happier now.

The 1999 S3 and X1 have the same engine, same ECM and map. I'd definitely go with the race ECM if you change the exhaust.

I have a 2000 S3 which I've owned since new -- You REALLY want to put the race ECM on -- Its like night and day. If Buell didn't need to meet Noise and Emission requirements these bikes would have come from the factory with the Race ECM a free-er flowing intake and a free-er flowing exhaust -- Thats why the Race Kit was offered -- they really do not run correctly in the stock configuration -- Don't forget to reset the TPS --
