Compressor surge? Options

[BudmannG]

What would case compressor surge?

I have gotten many answers. I was told it was because my bov is to tight? I have a rfl bov. I did not recieve said spring adjusting washers. So what would I use in place of these washers?

I am at wits end with this thing. I try to pull a wot and when I hit 12psi it burps out the turbo and then I get boost spikes up to 20 psi.

Bud, I cant recall what turbo you have. I know that I had an issue with compressor surge on my gt35 when I had the bov cranked all the way down (more pressure prior to release) once I backed off the tension, I had great part throttle control, at ot below 10psi.. If I allowed it (throttle modulation) to increase past that, she would buck and kick like a one legged man.

So either I run, nice and easy, making<10pis part throttle, or Im balls out.

One my ask what a one legged man kicks like... Well, its a hard initial pop, then it falls on its face... flops around like a fish out of water, chokes, pukes and sputters... Compressor surge on a dsm is somewhat bothersome

EXACTLY!!!

I was thinking that one of the two homedepot couplers were burping under pressure. I am going to run a boost leak test on it tonight or tomorrow.
I can only drive easy with part throttle. Even if I hit 70-75 it wants to flutter, and it doesn't matter where your pedal is.
I am running, supposed to be a 50 trim garrett, that is what the guy told me when I bought it.
