Default MSD Adaptor but still not working right?

I have spliced three different signals from ECU to MSD (Pur), SAFC, and VPC. The SAFC reads correctly, VPC is working well, but MSD tech adaptor acts up. When I first start the car it is working fine, but after I warm up the car and boost it really hard, RPM jumps and stays about 3 grand higher than normal. Any suggestions? Thank you. John
