Sweet!

Actually, I've been told that 3rd is the weakest gear in a 915. Hayden (WEVO) says it's too much torque at low RPM that breaks 915's, IIRC. His rule-of-thumb is 350 ft/lbs and 5,000 RPM.

I've got a 915 and never stand on it in 1st, because I did that once or twice and it was just scary. It's far too low to be doing that.

Conditions permitting, I rev in N/A mode (no boost) to about 3-4000 and then get into 2nd, roll the power on until 3,000 or slightly more and then stand on it until redline.

The higher gears, you're already spinning pretty good, so just shift and stand on it again until sanity (or fear) prevails. Cars in the rear-view which aren't dots at this point are going pretty darn fast.

With a better turbo, you gain the ability to treat the throttle less like a light-switch - because it'll start to spool sooner, and you don't need to stuff in full throttle to get boost.
