Ryan did a good job of explaining this, but there is another side to this as well.

Predicted Air flow tables must be adjusted to match actual, Your All Set No worries.

i just got off the dyno .... Patrick G made all kinds of adjustments and its still closing around 6500 rpms... besides that everything is great... he spend about 3 hours working on it this morning... Talked with Nick W. as well him and patrick are gonna get together to see what else needs to be looked at. Hopefully we can get it right!!

This was the old version, reset codes and continued. Still was interesting to see this happen live. I believe Blue is awaiting the upgrade version.

What about centrifugal blower set ups that are blowing through the tb instead of pulling?

So the upgrade fix for the origional NW102 doesn't work, the newer NW102, or both? Was just packaging mine for the fix.

Ted i dont think its in the tune.. As everyone knows Patrick is a complete tuner and very expierenced with big builds and high horsepower setups.. Nick is sending me a 1.5 inch honey comb spacer with a new tb with a stronger inlet.. Will be at LSX performance to get on the dyno Wednesday night to see how it turns out..
