You can gain a lot of usable performance by lowering the gearing.
The 996 has a 1.84 primary ratio combined with a standard (non-close ratio) gearbox that makes it probably the highest geared stock Ducati ever. I strongly recommend that ALL 996 owners change from the stock 15/36 94-link chain to a 15/43 98-link setup (or the equivalent 14/40 96-links.)
This lower gearing also raises your top gear rpm at highway speeds to avoid the 3,500rpm stumble and 5,000rpm half-throttle bog that the UM222 smooths out. If you don't experience this stumble the FIM chip won't make a significant difference. It will however run lean at highest rpm because the single injector pulse duration maxes out.
