You're probably right, and definitely right about any detonation. I honestly have no experience with FI, 450+ hp combos on stock bottom ends...so OP should listen to Surf'nsun.

6-7 and you’re safe, 12 on a stock lt4 is a disaster IMHO.
Don't know it's over 450hp. This is why I am excited to go to the dyno. Have to get some info before I start making decisions.

They dyno shop is a tuning shop as well. What I am paying for is 2 pulls on the dyno and a recommendations on how to improve.

This car is never raced. Heck, the Avg MPG in the car shows over 23.5. That should give you an idea of how it gets driven.

Default RWHP Projection

I'll say 435rwhp. And check the compression if you fail to achieve that level.

Old crispy, my trusty 88 4+3 z51 laid down 457/446 with a stock bottom end spinning the tires at 6,000rpm. (Car is very light, and the straps were poorly done) ($20 dyno day)

it won't last forever, but it sure is fun for now.
