Internals are in; so far so good! No apparent leaks or other issues as of this moment, which is something that I was worried may happen. Toughest part was that the stock piston DID NOT want to separate from the sleeve in order to be removed from the seal screw; when we finally got it out, it was super gummed up inside and took a bit of cleaning...I'm almost surprised I wasn't seeing flow issues with how sticky it was, but even at WOT I'd only seen it dip below 1600psi once -- and even then it still stayed mid-high 1500's. Other than that little hiccup, just took my time and made sure to follow the directions & tutorial video very closely, and it went more smoothly than anticipated. Now...on to more airflow mods!
