Diesel Bombers - 97f250. error code p1211 issues. need some good advice!

Hey guys, need some advice. Ive got a 1997 F-250 7.3 226,000 miles, automatic, stock exhaust to 4 in turned through box to 5 in stack, cold air intake rolling in 17 in rims and 34 in rubber. I bought an edge evolution for it about a month ago. I installed to level one towing settings cuz I primarily pull trailers and my everyday truck. I was greatly impressed with power and performance improvements! Truck ran amazing! Well curiosity called and I upped it to level2 racing setting. I pushed the truck hard(not pulling), smoke rolling, s@&t eating grin on my face!! I backed off and drove home. Half way home the light came on. Been triggering ever since constantly specially when warmed up and hot. Acts the same no matter the setting now. When code trips I feel it in the truck. Cruise control works but looses speed and shifts in and out of od alot. I changed fuel filter2000 miles ago roughly. Im wanting to install an electric fuel pump but haven't yet. When truck is hot has hard long cranks to start. Idles up and down 100 to 150 rpms difference. Mileage isn't bad but worse when light is on. Very very annoying issue!!! Someone please throw me some answers if ya got a remedy. Ive read posts saying bigger oil pressure units. Any ideas will be greatly appreciated! Thanks ya all
