I had a stock-sleeved B20/VTEC (only a block guard) with a HX40 turbo handle 400 on ~18 psi @ 6800 RPM (pump gas)

only problem is boost kept climbing due to too small of a wastegate, so boost cut kept killing it at 6800...

Its like everyone sais... its all in the tune... My timing on race gas is usually about the same as some of the other tuners pump gas timing...
