I tried searching and reading around for a good hour, but couldn't find the answer to my question. Searched "boost cut" and "boost limiter".
Anyways, I was cruising on a local highway the other night at around 80mph I punched the gas. Once I built boost and the rpms shot up my car began to "cut off". The car would jolt forward slightly then cut then jolt forward again then cut rapidly and repeatedly. No warning light came on, it just wouldn't pull if i floored it. This was different from my other experience with "boost cut". Awhile back when I had first installed my DP, I tried flooring it at 80mph also. That time, the turbos spooled quickly with a forward leap and kept pulling until 120mph, where i heard a "THUG" and the warning light came on, gas shut off for a few seconds. After a couple seconds the light went off and I had control of the gas again...the car seemed fine. I'm wondering if this new occurance is because of the boost limiter. So ultimately, my question is: What exactly happens to the car when you reach boost level and don't have a bcc? Are my past two experiences more than likely caused by that? And will my current problem with the "cut and go, cut and go" condition of my car be solved by installing a bcc?
I appologize in advance for the lengthy post.
