i tried to raise the boost past 9psi, but it would lean out way out of range. so @ 9psi was the best air fuel ratios.. left it happy at 9lbs..

I was unaware the stock ecu could run an extend port or larger secondary's. Nice work though!

stock ecu has limitations, but the trick is to take advantages of it's limitations..

I am amazed at this, your making around 100HP over stock, just with upgraded exhaust, fuel, and porting.

I know a little something about this. :D

This really makes me want to get my engines on the dyno.

best part about this is. this amount of hp is enough to keep most of us happy in a street car. not much went into achieving this hp goal. ofcourse some people want more, but the average rx7 enthusiast would be very happy with a simple set-up like this. I drive this rx-7 once in a while (when my kid breaks an engine mount, and drops it off for me to fix it) and i could tell you it's a fast and great car to drive.
