I'm not overly bothered by the result - it's lower than last time by around 6-7bhp, even though I've thoroughly refreshed all the pipework (+N249 bypass, all new vac lines, catch tank, no PCV, pressured tested with no obvious leakages) - it feels fantastic on the road and pulls very cleanly. It'll normally spike at 17-18psi and hold 15 which is about right for stage 1
I'm going to pressure test just the turbo very soon, just from the TIP to the 90° outlet to see if it holds boost as when I tested the full pipe run it was leaking down quite quickly from somewhere
