1. The infamous goose honk that is apparent on all of these designs. Had it on my BSH as well. It NEVER goes away.

MAF location. I personally wouldn't use an intake that forces you to remove the MAF sensor from the OEM housing let alone move it.

good to know the goose honk isn't weird. I have videos, but I haven't had time to work on them. Work is kicking my butt this week.
the MAF location was my initial concern, I'll see if it happened in my video so I can iron out the issue.

there is only 1 way you will "iron out the issue"... lol.

you caught my underlying thoughts....
Im not seeing this surging boost issue your talking about? At first i think it might have happened for a few pulls but after i put about 20 miles on it or so it seemed to stop doing it. When i took it out for the few miles or so, i did a few wot runs, im not sure if it helped with the surging issue that your having. Heres a video of me in 6th at around 60mph and WOT, no surging.

Impressions, i really like it. Its not super loud when getting on it. Is has a nice tone to it, and the blow off noise isnt crazy loud but i like it. Seems to pull more up top. The install is very straightforward and overall i like the look, it compliments the bay really nicely.
WTF, all this oil in the stock intake from the pcv, (why the hell hasnt anyone made a pcv delete kit?)
Heres what it looked like opening the box, all the stuffing paper taken out.
Stock stuff.

Every car is different, the homeostasis for your car may have been a -5 LTFT, when adding a CTS intake it may have put you at LTFT +5 which would've been within spec. If you have a car that has a LTFT of +5 to +10 adding a poor intake design would cause an issue.
Normally, the intake will cause the MAF to read less air than what is entering combustion making our closed loop system think out car is running lean and add to the LTFT. Maybe when CTS made this intake they had a car with a fuel trim that could handle the intake and felt the design was "okay". They'll realize as Forge did that a percentage of users will have problems with their MAF location.
Sure i guess. All im saying is that im not having a surge issue at this point. Im not saying that it will never happen. I believe that running the car at wot after the install may have something to do with the surging issue and might have helped the ecu adapt better to the intake.

Your car would've surged at WOT initially no matter when you did it. It needs to collect data for high load situations, when you went WOT it noticed the MAF values do not have the same correlation with the AFR and hesitated to correct it.
An intake should not have this issue, it's why keeping stock MAF housing and location is important.
It did have a "surge" at first (if you want to call it that), but after putting about 20 miles on it, it slowly stopped until i didnt notice it anymore. The cts intakes uses the same diameter pipe as the maf housing, but as far as using a different maf location idk, but its not giving me any issues at the moment.
