Intense boost fluttering at WOT *updated with pics*
I have had my car back together for about a week now, and i've been slowly adding boost back in, I started at about 14-15psi and slowly turned it up to about 20, but after the last time I turned up the boost (to 20) when I'm at WOT the boost fluctuates rapidly between about 15-20psi, just shoots back and forth real fast, what could the problem be? I think it has like a 6psi spring in it, its a knockoff external wastegate, could the spring be too small for the amount of boost i'm running?

sorry to bring this thread back but the problem resurfaced.
I put a 1 bar spring in it and boost holds rock steady at 15psi, now when I turn the boost up (still my homedepot mbc) it still flutters like crazy between 15-25psi. I just purchased an electronic boost controller but its not here yet so we'll see if that helps.
