That's right, don't expect much more gains in the upper RPM range, but expect improvements in the low to mid-RPM range, where we do most of our driving...that's what people are reporting and dyno charts are showing. Optimizing A/F ratio is the other big bonus. The other previously mentioned features are minor bonuses. The Uprev tune is good to have whether or not someone intends to do forced induction in the future.
