Most likely won't be doing any future logs with the stock intake.

However, I have a bunch of logs that I've done with the OEM (modified) intake. What are you looking for?

Is the dip between 4700-5300rpm on the stock intake consistent? Are your old logs on the stock intake with the same Uni/JB4 stack settings?

Yes they are.

Just to make sure I understand, are you referring to the VDyno logs or the Datazap logs?

Here's another VDyno log (last year) with the same setup
OEM modified intake
Uni DP
Uni Stg 2 ECU flash

Again, approx numbers since this dates back (Nov 2017) and I had to use a site to find previous weather conditions on that date. The log was done in 3rd gear tho so again these aren't identical in comparison

Same dip in the mid-range (4500 - 5300 rpm)

Haha! wait till you find one on sale OR buy a used quality closed system

I think the biggest difference is a closed system that offers a better front air duct. Essentially forcing all the frontal air into the intake stream.
