Yup T25 spiked all the way up to 18 PSI. Held it there for about 3-5 seconds then blew off IC Piping (prolly a good thing). SR took it like a champ. No leaks, no blown gaskets or any other bad things. So today I took off the mani, turbo and turbo exstension and decided to check everything out to be safe. No shaft play whatsoever. While it was off the engine I heat-wrapped the manifold and ported the wastegate hole to match the flap (hopefully this will prevent future spiking). Over the past 2 weeks I have been boosting at 10 psi at higher RPM's so I knew something wasn't right (no Boost Controller was hooked up). Took it for a test run and noticed I have a huge exhaust leak at my downpipe, so I have to fix that before I find out if what I did was good. T25 definately spools slightly faster (I think the heat-wrap helps in that area), but damn...I'm missing 10+psi.... .....So that was my adventure for the weekend. BTW 18 PSI felt great, I was well over 115 too quickly...I have no speed limiter and I have a Mine's ECU, I have yet to find a rev limit on it but I don't rev past 7500 as there is no point.
