no we didn't PURPOSELY put 13 psi through it lol.... it spiked and held from 7-8200. on the very last run, we shut down after that. believe me i'd be takin bets on that it wouldn't last 2 weeks lol. but yeah we just ordered the 8 psi spring and we'll re tune it hopefully this up coming friday. TRUST ME it wasn't intentional in anyway... sigh stupid external wastegates!
