Thanks for the info, most people are way too influenced by the placebo effect. In my opinion the butt dyno has a instrument limit of error of probably about 75-100 HP, that means the butt dyno cannot properly detect any HP increases below about 75HP and is extremely imprecise.
Anyway, it seems like to me from the logs you took you are reporting a 2kPa change in manifold pressure and 52lb/hr increase in MAF? That is a significant increase in MAF flow.
