That sounds about right. In the warmer weather with the 3.4 pulley on, I was getting about 160 after 2 consecutive HARD runs, still no knock.
There's a table on the timing tab that adjusts timing according to IAT's. I used that one to pull some timing when the temps get way up there. I think it's a bit conservative, the way I have it, but I don't ever see any KR.

Thats great Nathan. I'm going to eventually have a few questions for you.
Once I get the cooler on, I'll start tuning it seriously. I'm not sure what to do about fueling after the MAF goes static. I added to the PE table progressively larger values ending with 1.32 in the 6400 blank, but it still went very lean according to the O2s in EFI. I need to check fuel pressure, log my pulse widths, and hook up my wideband.

Mine go down to as much as 890. I try not to let them go under a static 900 though, so the 890 is just a dip.
I did the same thing on the PE table. I've YET to figure out a better way. Hptuners is suppose to be coming out with a way to extend the VE table on to 200kpa and even 300kpa in the future. If/when they do that, I'm going SD if I still have the blower by then. I bet it would run tons better and a lot smoother that way.
Do you have a hesistation from idle with that thing? That's in the VE table too BTW. That's supposedly VERY common with the SuperChips tune.

I have a feeling it will run some nice times. It ran mid-high 13s N/A before the radix. I opened a couple of older EFI logs to compare todays with. My run today was only 2nd gear from 33-83 mph. Thats +50 mph in 6.0 seconds. Reading old logs, the same 33-83 mph range took 8.0 seconds. There is a 1-2 shift in that range though on the old log.
To make a fair comparison, 2nd gear on the old logs is from 51-81 mph. It took 5.2 seconds to make that 51-81 run. Today, that same time slice took 3.7 seconds.
