It feels alright on the street, I have nothing really to compare it to since I never got to ride in it bone stock and I've only raced a few cars, all of which weren't much of a challenge.

[QUOTE=xblazinlv]The car is running non-sequential
As for AFR, the richest it goes on the graph is 10.7 if you look at the bottom it says the minimum AFR, average, and max.
I am not sure why the compression on my rebuild with less than 2000 miles on it is so low. The car had a proper break in and never saw more than 9psi of boost until the dyno night, and even then it is tuned extremely rich with retarded timing.

I can't see your dat file..but here's my observation...
First off, when you look at the numbers at the bottom, for AFR switch the numbers, 10.7 is the max, 13.9 is the min. With that said you are running too rich...shoot for min 14.7 at 0 boost and below and max 12.0 @14.5PSI. This will work better with retarded timing. Chances are that you have a lot of unburned gas in your emissions when tuned extremely rich with retarded timing. If you simply advance the timing you may see more power but you will still be running too rich.
...it's always best to know the condition of your motor (compression #'s), your ignition system (misfires in wideband log, emissions) and your fuel system (fuel pressure, injector pattern) before doing any performance tuning.

Your engine if fine.
Your transition needs more fuel. For being non-seq you should not have that spike.
10.7 is rich imo for below 10lbs.
Intake temp will make a huge difference in power especially depending on your ign and fuel intake correction maps.

Massive boost leak FTL 
Atleast that explains my issues. Thanks for all the input guys, turned out to be a massive boost leak from the back side of my UIM. One of the vacuum nipples I capped off when I went non-sequential was gone, and it would barely hold 3psi of pressure with the pressure tester. Fixed it, and it instantly held 15psi in the lines and shot the pressure tester off into my face lol.

It really is an art form, I've seen cars (mustangs) "tuned" by average joes (no lie) get onto a dyno and make 470rwhp then the "PRO" puts down 620rwhp with 3 pulls..I know it sucks trying to find a good Rx-7 tuner...but it's well worth it.

While I agree with you to a certain extent, I also disagree.
I'd love to pay Steve Kan or another big name tuner to tune my car, but unless they come to Vegas in the near future, it just isn't an option.
Luckily for me Guitarjunkie lives 3 hours away, and is a pretty good tuner from what I hear. He is going to come up this next weekend and tune my car and Gonzz's GT35R 1st gen.
