I'll find a diagram that shows how to plumb in the dawes and needle valves. Maximum boost is 16-17 Psi, any higher and it will sense overboost and go into limp mode.
Engine cover fits back on as normal, although I fitted washers to space the cover up slightly off the intercooler to stop it rubbing.
There may be a slight drop in pressure across the intercooler, that's why I fitted the pick up post cooler, it shows you what boost the engine is getting.
