Seems a bit low, check for leaks including injector head leaks

About 20 lbs a min lower than i would imagine it should be

Boost sounds about right, check out the wastegate and what tuning software are you on aem?

Ok but still seems low for hx40

 

[Patrice tardif]

Is why i ask for opinion but the top end is f***ing freak pull to 9000rpm no high egt compare to my hx35 in the bep55

Smaller housing and wheels will yield faster spool for sure
