i'm def starting to think it's running lean. i think my mechanic replaced all the muffler / exhaust pipes they didnt do a full fine-tune , im gonan try to push 1/8 the adjustment scre to make it tad richer and see

also watching a bunch of videos of lean vs rreach sounds it sounds not about surging but the oppsite.. i think we are closer to the culprit
