So last night I replaced all of the springs, cupseal and orings. Ran stock valve spring and blue mainspring with Valken Infinity paint (not the best but still better than most field paint imo) and it ran wonderfully. Sun was out, slight breeze around 70 degrees with 275 +/- 8 fps. TPC was more open than normal with the blue spring but was still getting around 170 shots off the 13/3000. Thanks for all the advice guys and to the OP.... Shoot good paint and fiddle with the spring setup!
