cuts out when i build too much boost??
 

K here is my situation: I got a pettit racing motor just put in my xs, yes i know, i have heard quite a few bad things about them but i'm praying that I am an exception. well anyways they put it in it runs beautiful and i broke in in over 500miles and i decided to go above 4k now. I changed my rev limiter to 7600 and checked my boost lvls which read:

1. .50 2%
.50 2%
2. .85 62%
.90 64%

B4 i went into xs setting 1 is what i changed to change my boost lvls. when i saw this i thought ow maybe they switched it to setting 2.... Ne ways i put setting 2 to .85 and 62% for both of them and went driving. When i started boosting in third at about 4.5 i would hit 1.10bar and its as if i hit the rev limiter, the fuel gets cut, i'm assuming. Now i have no idea why it is doing this. why am I creeping in soooo much boost? And i'm assuming that the fuel is getting cut because i'm creeping too much boost.

I have a PFC cammander single turbo street port 850cc prim and 1600cc secs and walbro fuel pump.

One thing that I am thinking is that my boost control unit is broken.
