Any turbo kit you go with is going to be a low boost application since the engine has pretty high compression.

The adaptive learning strategy in the Yaris ecu is very rough to over come with even 8 psi.
Trust me I'm working on it as we speak. Its nice to get a few WOT runs clean, but never consistant. It takes alot of time to tune this particular ecu. At least to a point where it WILL be consistant.
I've tried a new approach lately that seems to be working much better.
