bad mbc or wastegate?

i installed the ets 57 trim kit and today tried to up the boost.. the mbc was all the way down and i hit 16-18psi... ididnt pay 100% attention. no matter what i do, every click or turned all the way or half way up the boost wont change. i even toook off the line going to the wastegate from the mbc and no change

whats wrong here?, car is supposed to go on the dyno 2morw and i dont want to have any problems

boost leak was done and just a minor one at the throttle body seals,. nothing that would effect that much

Sounds like you might have the MBC, setup wrong with the tial wastegate? This page should have the install instructions for the wastegate,

Make sure that you have the boost line going to the wastegate attached to the TOP of the wastegate. Take some pics of your current setup. I don't believe that your boost controller would have all of a sudden taken a sh*t, but it's always possible I guess.

Check your wategate springs. Same problem I had with the TT50trim. They had two wrong springs in it.

Go ahead and disassemble your MBC and take the ball and spring out of it, then replace both as they were. Sometimes the ball and/or spring gets stuck which will not allow you to adjust your boost.
