I just took a couple videos of the tach & speedometer at WOT to about 7500rpm from 1st to 3rd gear. Of course you can't feel the acceleration from a video - *try to watch this without the suggestibility factor from my original post which indicates I thought it was falling flat after 6000rpms*

Oh and the lights on the dash are the door open sensor, and now the battery and brake light are flashing intermittently, which I believe is because the belt for the alternator is wearing out.
So anyways, I took my gf for a ride in it, she knows nothing about cars, or even what an engine does, and she said she thinks it feels "the same" as it did before with the stock cams & springs, so it's possible it's in my head and/or Ben at JWT is right and the motor is being restrained with the small header (hotshot 3rd gen) and 2.25" cat back exhaust (the exhaust note is fairly quiet but the cold air intake, which is a 3" is REALLY loud)
