Question How do you Tune a 13B Turbocharged Rotary engine?

I have spent a lot of time on Dynos only to find that my Tuning is way off when I race at my local Drag Strip.
My car is equiped with digital AFR (Air Fuel Ratio) and EGT (Exhaust Gas Temperature) Meters. I have been very sucessful tuning my RX7 with these tools.
1. Does anyone have a baseline for Tuning a Turbocharged Mazda Rotary Engine?
2. What is considered safe EGT readings?
3. What temperatures are considered dangerous to warp Apex Seals?
4. What is considered safe Air/Fuel Ratio readings?
5. How accurate is a AFR reading on a Turbocharged Rotary engine? Since these engines can be tuned to run so rich and still make massive amounts of horsepower.

Thanks
Albert Mets

You have a lot of reading to do my friend!
There is a search button up at the top right of the screen next to that fancy red 2nd gen.
It will enlighten you to all of your perceptions and misconceptions about this car quickly with careful reading. Good luck!

i second that. lots of reading. its not that noone wants to help, but this stuff has been discussed before. not that there would be NO more conversation about it, but a question basicly saying "i know almost nothing, teach me everything" is not going to get the best replies.
a few quick freebies.... apex seals usualy crack.
AFR wont be acurate at all in any car if you are talking about a 1v O2 sensor. are you asking about a wideband?? or like a greddy a/f meter... aka... "worthless light show"?
