Yes, massive room for improvement. Which I expected having done this once.

Thanks for all the feedback. Validates my own thoughts on what needs focus. I think this Wednesday night I will try a few things including shifting in to second earlier. I think I might try shifting before recline. If I remember correctly my hp peaks at 6800 or 7000.

*Edit: Using the 91 octane tune numbers.*

- So my torque ramps fast and starts its gradual decline at 3500rpms.
- Torque and HP cross at 5250rpms.
- From 5500rpms to peak HP at 7250rpms the HP difference is only 10%. By redline I've lost that 10% and am back down to 5500rpm HP.

My thoughts on what this tells me...looking for validation or correction:

- If I launch at 3000rpms my torque is a full 100lbs less than 3500rpms. Launching at 3000rpms vs 3500rpms should help to keep the spin down. ?
- I should shift from 1st to 2nd at 5250rpms. Landing in 2nd should put me at peak torque. If the R-S3s are warm I won't spin in second.
- I should shift from 2nd to 3rd at 6500rpms which will land me at 5250rpms...right when HP overtakes torque.

Finally...4th. As I mentioned on Wednesday I ended the 1/4 mile just a tick shy of redline. I'm 'thinking' that I should shift from 4th to 5th at 7000rpms. At 7250 it drops like a stone so I think it would be better to shift earlier than later or risk the chance of shifting too late. I might even do it at 6500. But the car pulls sooooo hard in 4th it is hard to not let it have every moment it can there. But it has to be better to get the car in 5th sooner than shift 10' from the end or even worse hit the limiter and watch it suck out the power.
