Exhaust gas pressure limits?

[Badger]

so the only thing i havent changed was the crankshaft or the oil cooler. oil doesnt over heat so ill change it when i feel the need. and as far as the crankshaft and oil flow, i guess ill risk it while running my 40 psi of oil.

but anyway, i have the smaller turbo which is 75mm exducer VS the 80mm exducer larger turbos. they both acted the exact same.

the latest tune i had done was for a cpl 8518 , 4/6 timing engine.
