Adjusting those parameters may help with the slipping but the centre diff has always been the issue with the 4th/5th GEN 5EAT as the 5th GEN has almost all of the same internal components except the valve body.
People have smashed the intermediate shaft, planetary gears, pinion shaft, and needle bearings on Far less power , I know someone who had a fully built 4th GEN 5EAT (Clutches, frictions, steels, Shotpeen , cyro treatment , valve body mod, brass bushing upgrade) and smashed center diff 2 times at only 330hp!
