After deleting my cm871 cpl 2732

[Zeus818]

I have two questions you gurus can answer or help me out with! So to start, I have a isx 450hp cm871 cpl 2732. I got deleted and tuned to 525 @ 1850 ft-lbs which is what mechanic suggested as long as I’m not flooring with heavy loads. I read that max power for my engine is 475bhp @ 1750 ft-lbs after doing research about my engine. Will my motor go kaboom or is it okay where it’s currently tuned to? Am I risking anything severe?
Second minor question is, I have a blow by smell but no physical blow by. I consume about half to a 1gal of oil every 10k miles. No oil dripping, just smell but no visible blow by. Just wanted to know if normal or not? If not, what should I expect?
