Default Expected boost levels with Cobb Stage 1

I read somewhere on this forum that people saw lower boost levels in lower gears, but higher boost levels in 3rd and higher. I can't seem to find this post again.

I installed my AP last night, and according to it's live boost readout, I'm getting around 12.8 in first, just over 13 in second, mid 13s in 3rd, and topping out between 14.3 and 14.8 in 4th. No chance to do 5th gear runs yet. Does that sound about right, or some wastegate adjustment in order?

You are right at target boost.

Sounds right. First gear shoots up so fast I dont think the turbo can hit target boost with stock turbo.

Thanks for responding, that's good to hear. The performance is better than I expected, so I have no desire playing it safe and leaving things where they are.

Anyone have experience going between the 91 and 93 octane maps? I've been running the 91, but the standard premium gas around me is all 92 octane. I wasn't sure if the 5 HP difference was worth the risk of knocking.
