Thanks, and that is hilarious about the 911th post...I wish I could claim I planned it that way!

This is my first rebuild and tune of an entirely new motor setup, so I can't really say anything either way about the 993 cams from an ease of tuning perspective. I know that the first WOT run on the dyno was about 235 hp, and there wasn't much the tuner could do to change that despite trying several things, so I guess you could say it's "tolerant" or "stable" relative to fuel and timing. He spent a lot of time smoothing out the torque curve as much as possible. I think you can also see the intake reversion at lower RPMs, but I think that's the nature of the cam and part of what I wanted in an engine with more of a broad and usable torque curve over peak power.

I think this motor could make much more peak power with smaller intake ports and valves, larger primaries, and a more radical cam, but it feels great like this. The biggest problem is me constantly driving in a low gear so I can rev it to 6-7k with the windows down and a huge smile on my face just listening to it...I need to be careful and get on a track more often!

I can also recommend the ID725 injectors even though they are way oversized for this engine on paper (and crazy-expensive...I'm saying they are effective but not cost-effective!). I got all the deadtime and small pulsewidth information from Injector Dynamics with them, and they are very tame at idle despite being capable of flowing so much fuel. Just in case someone needs a streetable idle and massive quantities of fuel elsewhere for some reason...still overkill for my application, though...I certainly could never overheat them with this engine! Probably the most impressive outcome of the tuning session was that the car now idles just like any modern car.
