I have a cobb ap stage 2 tuned bugeye that seems to be studdering or hesitating under low throttle and rpm. Between 2-3k rpm and I havent been able to figure out what is causing it. Any ideas?

Yes, third gear from 2000 to redline - AFTER you fix your clutch.

Clean and check your bov. The txs has caused some leaking issues for people. Or swap to your oem just to check to see if it solves your issue.
