i was on here a while back, i had problems with cranking compression and missing horsepower, but since then i've been doing a lot of research. i also decided to have fun and purchased dynosim. has anyone had any experience with this program at all??? i know how to use it i just want to know how accurate it really is?

what got me thinking is the TRICK FLOW 490HP top end combo. i entered in all the information and dynosim said approximately 415hp would be had. but then i have read articles in car craft, super chevy and other various resources around town who've had this kit, and they all say that TFS rating are VERY conservitive. and the kit should make 490hp minimum.
BUT, then i plugged in all the stats on my motor and two other friends motors, and it was only about 10hp off (high or low), what our cars dyno'd at.


any help please........thanks
