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.

ok cool! One last question I just want to make sure im clear on this. Did you dyno the car with the first 3 mods listed, get a xxx.xrwhp number and then dyno it AGAIN after you ported the TB's? Sorry for all the questions, I just want to make sure I know what you did and what agins are made with what. Thanks for the replies bud

I have 4 TBs

those that I had with my spare HR engine which where modified and the un modified VHR TB that were also used

yeah those test was done back to back , same day , within an hour with a previously tuned map for each component for a proper AFR

I also went on the dyno after every mods to be certain that was giving power...
