Decided to throw mine on the dyno today since it was a dyno day and got some numbers. Put down 366/345, that's up 34 hp from before the cam. The most interesting thing is we found out the wideband my car was tuned with is bad, my a/f was 10.8-11.1 the entire run and we had it set to what we thought was 12.75 so there's a good chunk of power left once the new wideband comes in. 
My setup is a 01 Camaro with full exhaust, sns stage 2 mild, and K&N hot air intake.

I would expect 380/365 from your set-up.
I apologize, but I am still answering emails from two days ago. Hopefully I can make my way to it today or this evening.

Agreed. We see best power at 12.4-12.8. Our dyno's wide band is always .5-1.0 leaner than the wide band we use to tune with.
Most all dyno wide bands read like this from what I have seen, but I'm sure there are some or a lot that don't. I feel it's all where it's positioned in the exhaust.
I prefer a bung or pulling a narrowband temporarily.

85mm MAF, Fast 92mm combo, 42lb injectors, SNS 2 cam, Kooks 1 7/8" headers, 3" y pipe empty cats through slp lm1 and 2 chamber spintech, yank ss3800, 2.73 rear
358.9 hp 327.2 tq
Putting off compression test for now. I just heard from speedinc something with their dyno brake was dragging and is getting fixed. Car will go back next week to see if anything changes.

well after all the extra work with flycutting and waiting for the extra part i decided to go with my car is running on a base tune.
hopefully martin ca post one of the idle clips on here since i couldn't figure it out!
can't wait to get it to the dyno now

There is no way you can tune a vehicle properly with an exhaust leak before the wide band sensor you're using to tune.
Now after the wide band sensor and narrow bands he could care less as no data is being sent to the ECU past the narrow bands, but you're probably right.
That and the dyno's wide band is all the way at the end of the system, I just don't see how it can be 100% accurate.

Jonathan is very **** about exhaust leaks before the wide band sensor we install in the collector.

IMO, even with a perfectly sealed exhaust with no leaks at all up to the tailpipe the WB sensors is always going to read leaner then that actually A/F ratio when checked at the trail pipe since you'll have fresh air influencing the sensor readings.
