Custom ported and CNC throttle bodies, upper and lower manifolds

Yes, i am saying tune before and after not tune only after because then we have gains from the parts and tune which doesn't give us a clear idea of what the parts did themselves vs what was gained form the tune.
We need dynos where the only thing that changes is the parts (with a tune for those parts of course, but not on a car that wasn't previously tuned before these parts were added)

Basically, we need a controlled test where the only thing that changes are these parts, not these parts plus a tune (no tune before) or these parts plus a CAI or anything like that. If we see that these parts alone give 10 or more whp/wtrq, I am sure many who want to max out NA power will purchase them.

Here or in another thread I tried to show this. The car ended up running lean and we couldn't show just the parts. We have to show the car tuned to the max before as that's how you needed to do it. then we add the parts and tune to the max again. Adding just parts doesn't work if the car doesn't like them. We end up seeing a negative or poor result. It also doesn't make sense to add the parts and show the numbers since that's not how the car will be setup. Kinda like gutting a race car and bragging you weigh so little when you've yet to add a roll cage.

Maybe before with tune and after with tune.

Exactly

Why would we show an untuned car, add parts, then tune and show those numbers? You'd be showing a tune plus parts then. That'd show you just cheating and saying the increase was something it's not.

This is as good as it's gonna get on a 2015 with cai, lth, and cbe. The 306 is tuned with no ported parts. The 316 is tuned and ported. The 324 is tuned, ported, and 5th gear. I don't know how I can make it any better.
