I took my silencer ring out of my pro-52 and it completely quite barking, big bonus,I havent tried it towing to see if removing it helped with the low rpm surging. My question is can removing the silencer ring effect performance or peak boost numbers?My boost is down a few pounds but I have done a few other changes at the same time so i am not sure if this would be the cause or not. My 1/4 mile time is also down a little.
