Just wondering if i can install my UICP and Intake without a tune, ive been hearing different things, some people say install it right before getting a tune others say its safe to install without a tune? i just need to know i dont want my car idealing weird and messing up

UICP. Yes. Intake... If not using stock MAF housing then NO.

Since you're new I'll give you a pass. Everyone is gonna hammer you and say search it out.
In short, you SHOULD get a tune because you're changing something in the air inlet/outlet system. Things are gonna read different. It also depends on what kind of intake (closed like AEM or open element like a lot of others), etc.

I put my setup in and ran it for 2 weeks before my tune; Doesn't make it right, just saying you CAN do it.
Even when using a stock-MAF-housing intake you should still get a tune. It's amazing how much the different intact tract and filter change the MAF transfer curve.
i have an injen intake and uicp, i will be getting a tune in about a month or so, and the MAF housing is stock i took out the sensor and put it on the intake

Make SURE you buy new couplers for the UICP. This can't be said enough. The Injen is notorious for it's short couplers. I ended up getting both blow-off (pipe seperated in the middle under boost), as well as a boost leak (even with the pipe together.) A lot of people recommend T-Bolt clamps instead of the ones it comes with, up to you. But while it's new, CHANGE THE COUPLERS!!!
as long as you don't run it for months without a tune...
Uicp yes. Intake I would not. Stock maf size ex. ets intake would be a little safer than a full 3 inch intake.
If you're worried about your warranty then get the following-
Cosworth Drop In Air Filter, Hardened Upper Intercooler Pipe, Light Weight Catback Exhaust.
These modification will not jeopardize the operation of your car.

If you do not care about your warranty, then get FULL BOLT-ONS.
I ran my intake for about a week or so with no tune but definitely would recommend a tune to follow soon after install
I'm looking to do this as well with my '14 GSR. Thinking of adding an ETS intake and UICP.

Could I get by using a Cobb AP and changing the MAF scaling table and load calculation tables to the ETS intake values in ATR? I know it's not ideal but it could work for an extended amount of time, right? At least until there's a tune involved. Am I thinking of it in the right way?

Your thoughts are correct but I would suggest multiplying the stock MAF curve by 1.025 for the ETS intake instead of using their published scaling. That will get you closer on the top end (which is more critical) at the sacrifice of the low end being a bit rich in places.

COBB's published MAF scalings need some work...

You'd be better off keeping the stock MAF scaling than to change to one with a leaner top end (lower g/sec values at high voltage).
Thank you, UT_EvoX.

I just purchased an ETS intake that is currently en route. I already installed an ETS UICP.

Here's my plan.. Correct me if I'm wrong. I'm still very new to this stuff.

Install the intake and multiply the stock MAF scaling table by 1.025 (UT_EvoX's suggestion) while changing the load calculation tables to the ETS intake values in ATR.

Does anyone else have input on the situation?

The plan is to safely operate (with these adjustments) and cause no harm to the car until I get all the necessary parts (exhaust, EBCS, etc.) for a pro tune. I'm looking at 6 months before I get all of the parts.

Does this work? Or is Cobb's calibration not safe for operation? I just want some consensus before I install the intake and drive the car on the daily.

Thank you.

Just multiply the MAF scaling as I instructed. No need mess with the MAP calculation tables until you go for a complete tune.
Just to clarify. I want to make sure.

Your MAF Scaling.

Stock MAP calculation tables. Not the ETS MAP calculation tables.

Thanks. Sorry for being a pain in the ass.
I installed the AEM intake with stock MAF housing on a cat back TMR (ralliart) tuned MR and have been driving it for about a year. No problems that I know of, it gives a little more power up top in the higher revs I think compared to the works drop-in which was a little quicker down low.
the car will read different once different mods are installed. i got all of my mods installed a week before the tune. once i left Massimo Power i drove home like a grandpa and didn't drive the car until the following week on my way to get tuned. like you say there's people who say they've been running for many miles like that and others who say don't do it. personally i'd say wait til you're soon to be tuned and get the most performance out of the mods you install. after all we do want the most gains out of our parts while being safe.
The ETS intake uses stock size pipes and the stock maf, so you should be good. Those are fairly simple mods and these cars come tuned real rich from the dealer. That being said, I don,t think that the little extra air from an intake should not cause any problems. To be safe though, I would not push the car until you get a wideband in the car.
anyone get to AEM CAI box connects to stock MAF housing?...so it wont mess up MAF scale etc etc...
Just don't go WOT too often until you get it properly tuned, even a cobb OTS won't even be sufficient.
