Dejon Tool MBC problems

[TampaBlunt]

I recently installed the dejon tool simple MBC with no apparent problem. The need for the MBC came when I replaced my T25 with a Evo III 16G and my new turbo only ran 7psi w/o a mbc. After I installed it I took it out and it stuck at a solid 10psi all across the powerband. The problem arose when I tried to adjust the boost. I turned it maybe 1/8-1/4 a turn to the right and when I took it out for a test drive it ran at 15psi until about 5500rpm in which boost kept on increasing with no end in sight until I hit the clutch. What the hell could have happend? Thanks in advance for advice.

mad boost creep or you didnt adjust the mbc properly.

i agree this isnt really an advanced technical question, you obviously have boost creep, i had the same problem my dejon tool, i got a new boost controller, and got a bigger wastegate(internal)

What exhaust do you have? External or Internal O2 wastegate routing? Sounds like boost creep. Pretty common occurence depending on your setup.

Do a search on Boost Creep and see if it matches your symptoms.
