initial tq with your present setup showed 494@5000, 507 @5500. your present tb's flow 2779 cfm, best guess. this is using 2.25" length on tb's.

the preferred dia. of the tb's would be at 1.75", or 44mm, lesser so 46mm. length of the tb's was 8.25-9.25 using eap, i don't have pipemax here to give a preferred wave tuning but can do later. cfm of this setup is 1793cfm. using this setup tq was 570 at 4500, hp was 556 at 5500.

i'm not sure how the tb length is measured but have a question in to find out for sure.

i'll go do a 1" shorter setup shortly.
