Turns out the duty cycle on the port injectors was getting too high so they swapped those for some larger, extended tip injectors. Just to recap, the car has a big bore pump (38% lobe), +30 DI injectors, and had 1000cc PI injectors.
The new injectors likely changed the spray pattern as they are now flush with the THP plates vs ~3/4” inside. Slight HP increase in 6th gear, but importantly, more power under the curve. I’d disregard the torque numbers as I don’t believe that is correct.

Yeah, I think something is not right there. It’s the first time they’ve ran torque number on my car using that dyno.

Definitely next weekend but might try to squeeze something in before.

Do you remember how much the 120mm TB/snout added?

So you're launching in 2nd with nannies off and using the manual mode's auto shifting feature. Have you found yourself short shifting the 2/3 due to tire spin?

I don’t. We never did an A/B test with just that being the change. I’ve heard it’s only 10-15 RWHP over the 112mm though. Perhaps it becomes more the faster you spin the blower, but can’t say for sure.
Yes to launching in 2nd, but I do not turn off stability control. Traction control is off. It typically doesn’t spin once I leave the line. It has happened a couple times, but it’s not a regular thing.

And you're launching from idle to WOT?

No, I’m leaving around 2k RPM in 2nd gear and easing into boost with Smooth Boost. Prior to that we’d ramp spark.

It replaces the vacuum based bypass actuator with one that can be electronically controlled by throttle position, time, etc.
