Great review , this will be on my mod list at some point . Definitely would like a bit more power from my current IE stage 2 tune.
FWIW when I installed my IE K04 (Borg Warner), I immediately noticed a noise similar to what you're explaining....I thought the turbo was bad, but I think it may have something to do with the fact that these K03+/K04's don't have a turbo muffler like our stock IHI's.Mine has been solid, i beat the piss out of my car, and its been running strong. Developed a kind of whiny sound like when K03s start to go bad, but its on the opposite side of the engine bay so im 99% sure it has something to do with my pod filter, not the turbo. WalkerT did some borescoping after multiple power runs on a dyno and a ton of street time and said the turbo looked good to go as a quality part. If you take a look at the top of the thread youll see them
I am currently on APR stage 2 I'm looking for options for turbo options since my current turbo has wastegate rattle, was there a significant difference in power on APR stage 2 tune? And is the turbo still holding up well?Mine has been solid, i beat the piss out of my car, and its been running strong.

ehh you will free up about 10-15hp to the crank i think based on butt dyno, getting an actual tune from someone is going to be your best option if you want powerI am currently on APR stage 2 I'm looking for options for turbo options since my current turbo has wastegate rattle, was there a significant difference in power on APR stage 2 tune?

Dang. Nice to know you can run a KO4 file with the KO3+. Im currently uni stage 2 and can tell the tune is lacking for the turbo. Was considering dropping a bunch of money for a COBB AP and custom stratified tune, but if I can just upgrade my tune to the stage 2+ from uni for only $150 without any issues I'm gonna go that route.Here is the dyno with the IE K04 tune. The turbo runs great on both software you get more low end punch with the IE stg 2 but the pull on the K04 software is impressive for a small body turbo. But it has its limit like the top end drops off after 6000 due to maxing out its capabilities
Custom tune for the win. Far better than a stage/ots tune.Dang. Nice to know you can run a KO4 file with the KO3+. Im currently uni stage 2 and can tell the tune is lacking for the turbo.
