Engine/Transmission (1998.5 - 2002) No Boost

Ok here's my problem. Went racing on saturday and found out that i can't build boost off the line. After i launch boost starts coming on. Had to make my nitrous come on sooner to get outta the hole. I can build 55 psi of boost by the time i'm in second gear. I have the Rad,Silver Bullet 66,mach 8's,Tst Comp,Van Aaken,Water Meth,and Nitrous. It used to build boost just fine on the line and now it won't build anything. Wanna know if anybody has had the same problem as me and how the fixed it. #@$%! Checked all codes and all i have is where the RAD comes into play. So any help that yall could give.

What has changed since the time you could build boost on the line until now? What convertor are you running?
