Depends on setup. My old gmc made 649 hp for a year or so and was fine. My lb7 single cab made 533 horse with a single 75 and bent a rod.

I'm actually not sure I don't have slightly bent rods lol I have a funny vibration in mine. Oh well if I do thought I have the problem solver on the stand now and will go in soon.

From what I've been reading on this site is pushing 600hp is playing with fire depending on how you drive it.

Id still be driving my DD/Econ 120hp tune the majority of the time and just hope my max effort tune for push 600hp. Does the spool time decrease noticeably with these turbo upgrades? Ive never riden/driven in a Duramax with an larger than stock turbo so I honestly have no clue what to expect
