Ok. I backed out the torque screw and am in the process of capping the lines.

The torque screw was threaded ALL the way in :s

Ok so with the max fuel screw apparently maxed....and with the torque screw threaded out about 3/16" and the Wastegate capped, I'm pushing 10max it seems. That's when I really get on it.
Not as much smoke in higher Rpms but **** does it ever dump it I hit it too early....cleans up around 2000rpm.

I'm going to thread out the torque screw a little more- I compared it to my old IP setting and it's still threaded in more than my old pump had it.

I just backed the torque screw about 1/4" back - should disable it completely. It limits metering valve travel, so even slight changes(near stock setting) will produce big differences in power, but it should stop affecting anything within 1/4"; you can see it if you take the lid off the IP.


edit:
Plug the hose so you don’t have a boost leak
I just want to point out that while this may be a good idea, our IDIs run so much air that a small boost leak(like the 1/8" ID of the boost line for the wastegate) will make absolutely no difference in PSI.

Now, a 1" boost leak, on the other hand(CDR hole)... that makes some difference. That's the difference between 7 PSI at WOT and 16.
