So I just got a CAI and a TIP put on my MS3, but from what I have been reading it sounds like after you do even a couple mods like this, you have to buy somthing like a Cobb Accessport to change the ecu a bit or it could damage the motor? Is this correct, or is JUST a CAI and TIP not enough to worry about it?
Importance of fuel monitoring after mods?

Those mods alone are not "unsafe" enough to warrant any ecu mods.
buuuuut....to maximize the cai's potential you can reprogram your ecu with one of the aformentioned programers
i have the mscai and hypertech. they compliment each other just fine and i have no issues

There is no real danger involved unless you dont install the intake and/or TIP correctly. make sure the fit is snug and retighten after the first few miles, and air straighteners (if any) are placed correctly
I agree with oaklandopen. Simple intake mods alone are not grounds for safety concerns on a gen 1 MS3. It's when you up the boost, start messing with timing and AFR's (tuning) and/or start messing with exhaust flow upstream of the CBE (big downpipe) that you start stressing the high pressure fuel pump. That's when you need to be monitoring and need to know whether you are exceeding fuel demands or otherwise having unsafe operating conditions.

the trims, are the ecu fixing the discrepancy, as long as the error is not so large as to be uncorrecable within the range the trims afford, the afrs stay fine.
when that level is exceeded, you could be lean or rich, but the ecu should throw a cel in that situation
If I remember correctly my LTFTs were averaging in the 14s, when cruising they were like 10. STFTs were 4 and under. I do know on the dash hawk once you reach 5.5 on the LTFTs it starts to flash but I believe you only worry when they are closer to 20. At the time I had nothing to monitor Afrs so Im not sure what they were. The car never ran bad tho.
Edit: Just wanted to add as well that Im not trying to scare you, (Haxir), into thinking you need a tuning solution, just letting you know what happened in my case. Every one of these cars react different to mods but I think you will be fine.

OP: From other threads I understand that your intake is an MSCAI. I'm not aware of any issues with it producing "unsafe" conditions or causing abnormal LTFT's so long as you have the air straightener installed at the beginning of the short tube containing the MAF sensor per the instructions. Orient it properly. There's a dot or mark on it that lines up parallel to the centerline of the MAF sensor. That puts the vanes of the air straightner rotated or "clocked" about 30 degrees to the right of the center line of the MAF.
As long as you have that straightener installed and installed properly, there is no reason for you to be concerned about "safety" based on your intake choice.
