"Greg,

It is possible that the DMD smoothed the torque curve and gained a little power. HOwever, one dyno run is not enough to verify that. Two different days separated by months and only a slight increase in power could be affected by many things including different oil, different engine operating temp, etc. You know what I mean...you could run 6 dyno runs in a row and see that for whatever reason you can have statistical variation of more than a few HP and torque. We need to see before and after runs from well tuned cars with a bit more of a dyno history...like yours unless you have done too many things since your last measurement.

I was comparing the UDP which is both lighter and has a smaller diameter than stock/DMD.
No way in God's green earth is there someone going to tell me I didn't lose power (significant power) going from a UDP 12.9oz to a DMD 1 billion lbs.
You are right I have made up my mind, and whats so funny I was expecting my engine to run as smooth as a cadillac or lexus, something, it was smooth but not that much smoother.

on another note: lets say a udp adds 5hp by itself
Fidanza releases another 5hp

but both together would work better.. adding up to more than 10hp combined. A lot of mods are like that, by each they are ok, combined they are better than the sum.
