Custom ported and CNC throttle bodies, upper and lower manifolds by Synergy Composite

Yeah it's custom.

Not really matching. The TB is 2.48" at its smallest ID point. On that is Z1 post tubes which go around the TB and any 2.5" OD pipe so I'd say their ID is more like 2.6". The sections of 2.5" OD pipe (like stillens cai) and oem MAF section are only 2.35" ID. Then like the MAF post tubes there's more silicon sections that will be 2.6" ID. So it's basically a roller coaster from start to finish.

Humm... I forgot you were still using the oem maf size.... there is some power to be gained after your testing with curent setup.

why would pulling the OEM MAF section out gain power? the stillen is the same size. since im not boosted and blow through, id guess as long as the MAF voltage isnt maxed it'd make as much power at 2.35" ID as it would at any other ID no?

no.

since the TBs is now bigger with a slightly smaller shaft, it can flow quite a bit more.
The oem maf tube is your next bottle neck on your system depending if your exhaust can flow freely the new setup.

what can help you understand my point is you don't want vacuum (restriction) into your intake at WOT. if you have a precise tool , I guarantee you there is .
