I've been following this for a while.
Yesterday, I scheduled a Dyno Tune as I'm just not happy with the mileage. However, after a few PM's with davej and re-reading this thread, I think I may cancel the Dyno and install an AFR.
Smokes, can you help with he o2 sensor installation details again for a Freedoms 4"?
Hardone2get, can you comment on how your LC-1 and Speedhut gauge worked out?
You won't regret installing the AFR gauge.
