I'll throw my logs into the data pool for others to look over.
Here's a log showing a 2.7 degree rise over a full 3rd gear pull. This is my car with the J-Line and I don't have any part of my bumper cut out yet. A full 30% of the IC is obstructed right now.

Here's one showing a 4 degree rise:

Here's a log showing from a dead stop through 3rd gear. This is a 1.8 degree rise:

In terms of fill time I looked at ETC Angle Actual for two of my logs and looked at the time to peak boost.
Stock: 1.09s from 1.87psi to 21.57psi
J-Line: 1.12s from 1.49psi to 23.78psi
That's a 0.11s difference versus stock but it's rising 22.29psi instead of the stock 19.7psi rise. Most importantly the charge temp rise is 3 degrees while the stock FMIC rose 21 degrees.
I'm not saying the DHM IC is not a great product... I just don't see it as the best option out of all the options for people with stock turbos.
