IS200t turbo issues
I've had my IS200t for about 5 months with 10,000 miles and noticed I am having problems with my turbo.
It seems like it's struggling to build boost as the needle fluctuates while climbing through the RPMS.
This happens under normal acceleration. It actually doesn't happen when WOT and when I drive slowly and stay out of boost.
There is no check engine light.
Has anyone else had this problem with the new turbo platform?
Would this be something that should be covered under warranty?

Boost will fluctuate under part throttle inputs that have slight changes in throttle input. If you are holding boost through WOT then you have at least ruled out a leak which is good. Its possible there could be an issue with the boost control system (solenoids, wastegate, etc) but this should throw a code eventually. Can you post a video of it to help show what is happening more?

I think someone had a similar problem and it was an actuator that was sticking. $150 part replaced under warranty

Terrible video but you can see a little of what I'm talking about at the very end.
The needle on the boost gauge will go up and down even when going at a constant speed with the same amount of throttle.

See post #21.
It was moved to performance.. not sure why. someone saw the word "boost" and assumed fast and furious type thread.

Sounds very similar. I do have a catback exhaust, but that's been on there for about 3 months without this problem.
I'm hoping it's the actuator sticking or wastegate. But thanks, very helpful!

Hey Guys,
I had my IS200t for 5 months now and had an invidia Q300 and BMS intake on it from 4 months....I started having this issue about a month ago but in my case it is affecting performance

would this issue caused by not letting the engine cool down after a long drive? the carbon and oil didn't run through the engine completely that's why it left sticking. i always warm up my car before i drive and idle my car at least 2 mins before shutting my engine off. all turbo charged engine needs to do this. my 200t is at 15k miles now and still no issues. car is fully stock though.

on the manual, it mentioned to idle your car to let the engine/oil cool down. it is recommended to idle for at least 36secs after normal city drive, and 2mins after highway drive. guess you didn't read the manual. i drive aggressively after getting off work because i can't wait to go home. i noticed that oil temp go up to 210F if i do alot of full throttle. that's why i need the oil and the engine to cool down. BETTER SAFE THAN SORRY. i got time to spare.
