the evo3 boost creep continues
http://www.dsmtuners.com/forums/sho...&highlight=evo3
jsut to let everyone know. That method didnt work for me I have alot of creep still. I ported it out as it says plus im running a external dump. I can go about 70% throttle now without creep. I have ran it off the manifold to the wastegate bypassing the mbc. I have worse control then and it creeps more. I have tried tieing the flapper open and i still build boost and if it is a higher gear then it still will creep to 20+psi. Tonight with all this done and the flapper, mbc, and everything hooked up, I am still htting 22-28psi in the gears.The worst part is it creeps worse in the lower gears than the higher ones.ITs really weird.
I have read most people also dont start building boost till 2500 rpms. For some reason i get 3psi by 1798 rpms. That was on the dyno. That was the first reading. All i can say something is different about my turbo. Not sure if its a good or bad thing. I am really frustrated with it, i think i am going to finally bite the bullet, buy a 38mm wastegate, and a tubular o2 housing for it and go external wastegate. Of course without knowing why mine will not control the boost, I am a little afraid. With the wategate passage wide open going to a external gate, it has to work i believe. I ahte to covert this turbo to external gate but i am quickly running out of options. If anyone has any suggestions or comments please share.
