Alright, I'm ditching the Balance Shaft Delete idea untill after the powertrain warranty is up or voided. Just too much risk if anything were to happen.
balance shafts kind of hit or miss, really if your only lightly modded i wouldn't bother with it. only when you start cranking up boost is when the balance shaft is supposed to be a problem even then im not sure how much of thats true, after removing mine i could see though. it weights about 25lbs.
