* Eliminate or mitigate the 135 degree turn that the runners make as they bend back under the upper manifold and go toward their destination ports on the opposite side of the engine.
* Eliminate the intake throat constriction just behind the throttle body in the stock manifold.
* Shorten intake runners significantly, biasing the VE curve toward high RPM.
* Increase plenum volume significantly, also biasing the VE curve toward high RPM.
Final result.

sorry for the crappy pic but it was from my phone.
The tb on it now is a DM ported to 57mm but I plan to put on a 62mm tb shortly. I have started to tune on 15-16 lbs of boost, and I am now running 30 lb injectors. I blew a vacuum line off the other night on the higher boost as I didn't have that particular line zip tied. It was fine on 10 lbs.
Here is a video of me swapping from the stock to the custom intake
