The tune will be safe and sustainable, I'd just be thrilled to make that quad-digit number to have a mantle piece. At the end of the day, what it makes, it makes. As the old adage goes, "track numbers matter, dyno numbers don't".
I'm hoping for around 1000whp on the stock bottom end, but I'll be happy with anything over the 846whp and 666lb/ft it made before. They're usually pretty stout until you make 700lb/ft with them, so it'll be close.
