Chuck,
Your boost seems to come up pretty slow. I think Dusty is right in that the converter is a little tight as it should be coming up quicker based on the chip settings. However, I see a couple things that could be hurting you down low. Yes, the A/F is pretty rich down low. I'd open up the alky box and turn down the "initial" to about 11 o'clock and start form there. You should be at 12 o'clock. Also turn up the main gain knob some to offset this. You could probably go down to 10 o'clock but this could lead to some transitional knock on the street as the alky is coming in softer. Its easy to adjust so just run as low as you can without getting transitional knock on the street. You're just basically making it a smooth ramp when the alky comes in instead of coming in all at once. As long as you keep the timing on the low side like you have it you can run a lot less alky down low.
The other thing I see is that you have the alky timing delay. You are at 17.6 degrees timing for the first 1.2 sec of your run. Not sure about the SD chip. Maybe change the timing parameters to even numbers to get rid of this? On his latest 5.7 and 6.1 chips he made this defeatable for the track. Good to keep the delay on for the street as there can be a delay while the alky pressurizes. No worries about that when you're building boost at the line while at the track.
But yeah, the PTC 9.5 nl would probably be a nice upgrade. I just put one in for the TH400 in my white car last night, so I'll let you know how it goes!
I see you are running 11.2 for your A/F ratio. You are running only a single nozzle for the alky so you might be ok but I'd try richening it up a little. I'm running 10.6 with a lot of alky on a dual nozzle. At 11.2 my EGTs were high 1600s and I usually shoot for high 1500s. As you add more alky you need to run lower A/F ratio. I made a table to see what corrected A/F ratios one should be running for various levels of methanol % added to gasoline, I'll post it up if I find it.
