I think you cant exceed a certain speed on the dyno. According to your previous post...in 4th you couldnt hit your target speed of 155mph. I think you accidently got it twisted. On the dynojet I was on I couldnt exceed 163.
If you want more midrange you should consider the motordyne manifold. The runners in it are a little longer creating more midrange power. We habe a similar setup so I can attest that I love the way my car performs.
Just remember, the only reason why your car read lower was because of the gear. Also possibly temp. Just curious though what was your targeted hp?
