Pushing the DMax limits

[SilverDodge]

How far can i push a stock lly duramax/allison combo before something gives? I have found boxes from 60-200 hp, plush you can stack them. I know that the transmission will be the first to whine, but curious how far i could take it on a limited budget. TIA!

I dynoed 844 rwtq on a Mustang dyno with Edge Hot Juice,exhaust and air filter on my LB7. Never hurt the Ally or anything else.
