2ZR Turbo Yaris

Didn't this kit claim 90 whp gains on a corolla? For that to be true, you would have to be putting 50whp down before the turbo! Something's off... you'll get it.

Yeah, something's definitely off since I'm only getting ~5 psi, and not consistently from what I'm experiencing and what Torque is telling me. Could be a leak, wastegate adjustment, vacuum issue, MAF issue and possibly (but hopefully not), a torque management issue. My tuner believes it's 'fixable' and I should see 180 whp once this is sorted. It still doesn't solve the issue of it being an automatic, LOL! Of course, if I could get some boost in the lower rpm range, then it would work better with the auto. Speaking to other guys that have the kit and the turbokits guys, I should be seeing boost come on around 3500, not 5K. Something is letting the boost go, or something is inhibiting it. And, thanks for the encouragement. I need it. LOL

As an aside, I have a lot more faith in what these engines can handle. After two or three pulls, I had to walk down the road because I couldn't stand hearing my baby scream anymore. LOL. The tuner knows his stuff and he said the car handled it easily. The engine coolant, oil temps and trans temps were all well within safe limits. I also have more faith in my trans. That said, I'll probablly take Trevor's advice and have him tune it in a way that's a balance between performance and reliability. Maybe in the 160 - 170 range.
