I have a r85 map i got from somebody on here. How do i know how high of boost it is tuned for? I compared it to the base map, and where the rpm and boost colum is the base map looks like it's tuned 24000 @ 8000 rpms. Does that mean i can run 24lbs on the base map? My r85 map has 30000 @ 8000 rpms?

 

No way you'll want to run 24lbs. I wouldn't run but 15lbs on any pump fuel map on the street.

 

Go read about Setting 3 Map Ref. The PFC manual also describes what they are.
All of that data can be changed to meet your specific requirements.

P rows are for vacuum to boost. N columns is by rpms. Thus they form the 20 X 20 matric for both fuel and timing.

My P20 row is set up as 17.5psi (21870) which is the highest that the stock map sensor can accurately read.

Power produced determines fuel octane requirements more than boost.
425hp at 10psi equates to 425hp at 15 psi if both air temps are the same.
Power makes heat and heat requires more octane.

15-16psi boost is about the normal max boost on 93octane with stock to medium ports.
