just finished putting the car back together about 2 weeks ago, whenever we hit boost it feels like it cuts out and hits a brick wall at about 5K. We had the mbc and it was boosting 9.3 b y the time it hit 5k, put the stock bcs on and now its hitting 14.1 but still does the same thing around 5k. took a video to help figure out what the problem is. it has a few mods, fmic w/ maft setup, 16g.
