Reason I'm asking is because I'm having an upper and lower ported right now and have my tuning done also by Seb.

Also wondering if I would benefit from ported throttle bodies to help out with the ported upper and lower.

And yes, I have been searching and reading, but haven't really found anything of use.

Many thanks in advance!

Hp gains with ported TB’s are obsolete, Throttle response will
Improve. It all depends who did your porting and how well of a job they did. Seb’s tuning is on point, but I have a knock issue. Don’t know if it’s a false knock or real knock, we did over 150 logs with race gas twice still kept knocking which I believe is false knock, but to be on the safe side we kept the timing down. But I ran with another Z making over 340 and we are neck and neck. I never went back on the dyno after the tune. Hey if you’re interested me and SS firehawk signed up for track day at Sebring October 7th through chin motorsports.

I'm not looking for HP gains "only" from the TB's, but everything as a whole. A little crisper throttle response would be nice also, though it's pretty good already.

I won't be able to make Sebring unfortunately.
