D3's STS-V pulley is only 10% overdrive and I'd assume the XLR-V pulley is the same. I see 13psi with my 10% overdrive upper pulley on my STS-V with stock exhaust.

Did you ever figure out what the problem is? I am in the same boat. XLR-V with the D3 pulley. Moved the kpa tables up in the supercharger tab to 230 and 210. Still only runs up to ~180 kpa. I can't find any more tables to change that make sense of the problem. I'll include the stock tune, since some were asking for it earlier.

Not sure, I came in after the pulley has been installed. They did make a couple of pulls stock on a dyno jet and it was like 375. Right now we are about the same number but the graph takes a dive at 5k. The blower is whining like it making some good boost but the numbers are not there. I'm thinking there is a table I'm missing or missing in the software. Tomorrow I may try to turn off the settings where the spark, fuel, and throttle can control the boost and see what happens.
Also log your boost bypass duty cycle and I bet you see it open when you don't want it to.

That was what I was going to turn off, till I got a quick reply from Bill about the IAT constant limit being set at 62%. So I changed that to 200%. Made it a bit better but still not as good as stock. There is a cam boost constant at 62% but I don't know what it is and don't want to change something I don't know about.
Turning off those three didn't help out...
Neither did upping the cam boost constant...
Look at your scan. At about frame 745 your bypass opens and registers 62% at just about 6K.
It does not close until frame 866 with the MAP pressure of 26kPa. So something is going on there.

I looked at a few of my scans and I see 12psi PRE IC and loose about 2psi through the IC so I register 10psi after the IC. That is with the stock pulley.
Tim and I did a few runs where I changed my MAP sensor to check the drop across the IC and found just about 2 psi.

We got it ironed out, it turns out that it was the IAT temp set at 62% limiting us. The other issue was I was recommended to take 4* timing out. It turns out it needed 3* more than stock, so that was killing the top end. With the D3 pulley and CAI we made an SAE 400rwhp.
So what is your psi reading now?
