Just got the second set of dyno pulls done. The measured results are a little on the disappointing side: +21 HP, +30 ft. lbs. (as compared to the +40 HP, +68 ft. lbs. that Rocketchip advertised). However, I will say that Jeff at Rocketchip impresses me as being more competent at what he does than the dyno operator does at what he does. So, though the numbers are what they are, my inclination is to give Jeff the benefit of the doubt. Again, in terms of my subjective impressions of the car's performance, the gains seem to be substantial.
Regarding fuel economy, it's probably still too early to tell (since so many variables come into play). But, thus far, I continue to stay in the 27-30 mpg range and thus haven't noted any improvement.
