Kim, Its your boost cut. Boost cut is set at about 14.5 pounds, but what is happening is that your putting your foot down in too high a gear without enough revs. This puts a lot of pressure on the engine and the boost goes straight up extremly fast!
I bet you take off from the lights, red line first, red line second, redline third no worries. But say cruising in fourth at 60, put your foot down and it does it. Always drop back a gear or two.
