What programming have you guys found to show the best gain in the lower RPM range. Granted we only have a few thosand RPMs to play with but more power below 2200 RPMs would be good.

i think that most of the performance enhancers will add to the bottom end - every one ive tried and its been just about all of them have greatly enhanced the bottom end, some do it better, and some have more or less on the bottom
