What's the oil psi run at 1100. Always wondered what these new low rpm touted engines run at for oil psi at low rpms. Is it like the old maxidynes running 80-90 psi? I'd be skeptical of running that below 1250-1300 after a delete. It's gonna be putting out some more power with higher combustion pressures after the delete. More air going in instead of burnt egr. Whole diff animal compared to a non delete mx. You're stressing the bottom end even more with higher cyl pressure with the delete. Lugging it now after the "tune up" I wouldn't recommend. It's going to produce more heat to

Runs about 60 psi lugging, it'll run 80 at highway speeds 1500 RPMs. On a cold start it's pegged at 100. No boost or pyro gauges but running it at the higher RPMs does absolutely nothing for power, can't even hear the turbo spool up til it starts lugging lol all of ours are like that
