Evo turbo testing and results
#16
hopefully tomorrow and the weekend ill be able to get some street tuning done and see what I can do about holding more boost. preloading the wastegate more, better boost control and ofcourse smooth out my AFR

alright! so finally figured out my boost control issues and have 2 new logs, also tightened the waste gate actuator more to see if I can hold more boost. the majority of the power band seems to hold well but still falling off to 17-18 psi over tired adding a ton go WGDC in the upper revs but redline doesn't seem to change, I attached logs, AFR seems decent, going try to work on it a little more. maybe even dyno the car again with this setup, also need to get a good video of the back pressure again with the new boost control settings, possibly be more now that I have much better boost curve

My personal preference:
AFR at 12.5 worries me when under 4000 rpm. Turbo spikes here and personally, I'd rather see 11.5 for that extra cushion. I can understand this for bigger turbos to aid in spool, but not on this tiny snail. (And bigger turbos wouldn't spike as easily)
