[QUOTE="Jon, post: 445164, member: 5219"] The baseline is the factory setting which admittedly is lean for EPA reasons. There was a complete article either here or FJRTech.com on the BJM and CO mod. A fella did it and then used an exhaust gas analyzer to check the results of the mod. It showed a slightly richer mixture, though not significantly so. With the mod the abrupt throttle response is gone. I might try tinkering with the adjustment (maybe +6 or +5), but so far I'm pleased with the result. [/QUOTE]
