I got a friend that is an ASE certifed an d he install my new act clutch, after 100+ mile breaking on the clutch I wanted to try how it do so I punch it on 1st(from a roll). It seem like the primary boost is find then when it begin to boost on the secondary it hestitated for a second then go full boost. When it went full boost(13psi) it started to go back to 12Psi then back to 13psi (back and forth). It seem like when the secondary begin to boost it hestitate?

 

PLEASE HELP!!!

 

not sure what to say about your boost problem but usally you break clutches in for 500 miles from my understanding.
