stock valve spring boost limit
i’ve got stock valve springs in my truck and i’m running about 30-35lbs if boost with the stock turbo. on the fueling side i’ve got 50hp DAP nozzles and edge ez tune. i don’t even really get up to 3k rpms. i’ve seen companies say that 35lbs is the limit. is this true? should i upgrade the valve springs? if so, 110lb? 103lb?
