Regardless, a bouce that big is likely the result of a huge vac leak. Are your secondary butterfly's closed all the way? What are the "hg readings during the bounces?

oh its not good. thanks for the info then. i was under the impression that 80 was the min. i used a regular compression tester with the little valve gone and it was old. the markings on the face were a little hard to read as it jumps from 70psi to 100psi in increments of 30 with smaller marks in between. i will try to get another gauge this weekend. the hg reading are like -5/-7@1000rpm and when she spikes up to like 1800rpms its like -12/-15. i will video the event hopefully today or this weekend.
