Must have really good pump gas wherever that is. Please don't tell me it's 91 octane.

I personally wouldn't try to go far beyond 600whp on 93 octane pump gas (built motor or not, stock turbo or upgraded, water meth or no water meth, upgraded crank hub or stock crank hub) .... so certainly kudos to that tuner for being on the edge of the efficient frontier.
