New charge piping.
The stock MSM intake piping is is not optimal with all its bends, 1.75" piping and restrictive transitions between hardpipes and rubber hoses.
I'm already using FM's silicon intake pipe on the hot side as it fits the ETD manifold turbo locataion and does not interfere with AC or PS.
I have now also got hold of the cold side piping but will try to use the SS throttle elbow that came with the BigE kit. Actually, that will be the only piece left of the Big E once I get rid of the FM China IC. The hoses are 2.5" ID and are very sturdy, stealth and flexible to work with.
