I have been getting 6 psi of boost creep when its chilly out which is when i run the car so
im getting scared now. my setup is 450cc, 190lph walbro, 14b internal gate, fmic,greddy rs bov, full 2.5in exhaust no cat, stock gst mani and o2housing. Its gotten so bad the other day from 60 my wheels spun so much i had to feather the throttle. I have been thinking about an external gate but i dont want to redo the downpipe to connect a dump to it. I have heard that 34mm flapper or so will solve the problem but may still creep 1 or 2 psi and ive heard its a perfect solution so i dont know about that.. On another note is it possible to add another wastegate and use both wastegates to provide two exits for the exhaust gas or would it drastically affect my spool or something i cant think of?? I was thinking i can leave the stock internal and it will open at 10psi and get an external with a 10psi spring so it will only open then and give me 10 all the way...
