Also, is there any better throttle response from doing that, that you have noticed? Thanks for your replies

the gain of 7-9whp is with this
Custom straight flow exhaust w/ Xpipe
PPE step header
custom CAI (similar to the stillen V3)
but it was also seen when I had the stillen shorty + test pipe over a year ago.
the gain has been seen on both intake manifold
my first attemp to port the HR manifold was only to smooth the edge of inside the intake runner when they glue the base to the intake manifold.
the VHR was modified yesterday.
as far as throttle response , my answer would be it was unchanged.
