If you are ready to believe any claim from a guy who isnt showing any dynosheet and doing those test without doing it properly to really find what modification give what.
go ahead and blindly believe it.
the stillen header has never really gave anything and we never on this board proved it was giving much more than a few whp like you say ... 5-7whp at best.
that porting giving about 10-15whp is indeed hard to believe.
unless it wasn't tuned correctly previously or at all.
the topic is about the lower intake gain but the OP added another variable which we wont know what the lower intake can provide.
