I am not going to run that stupid low drive air hose over to the passenger side BOV. I have the HKS SSQBOVs and I am not going to mess with those in any way. I have read and researched this mod and it makes sense.... the JWT ecu only looks at the driver side intake not the passenger side. The reason for the air hose to be had is to shoot the air at idle to the other side to make for a less rich idle. Not only that, who in the hell wants that huge ass hose in the way anyways? not me. But besides that..... I have read and read and read on this mod and have seen some pretty good outcomes over its tuning affects. See with the one MAS being seen by the ECU there is no way for the ecu to see what the passenger side is seeing or reading, with the 2nd mas the SAFC can be set on this mode I forget what its called and the ecu will effectly learn the read out and thus being able to tune the car much better. From what I have read we are the only cars that can hook up this setup.........I am glad that you hooked me up Zhound my shop owes you one!
thanks again!

Whats so stupid abut something that works perfectly? A dual pop reads half of the mass flow into the engine and the QA table of the ECU is chaged to reflect that part of the reading. The reading is non-linear but the QA table is corrected for that to provide the proper a/f ratio. A twin POP is a highly developed very sucessful system that is quite relaible and can produce a lot of power.
You better reaseach what the purpose of the lifter "kit" you are putting into your motor is and what it's supposed to do. Often aftermarket mods actualy perform worse than stock. I don't know what mods could posibly be done to the stock HLA's other than to replace them with solid shim under bucket lifters which has no advantage unless your are reving past 8k rpm which is in itself no advantage unless you are running huge turbos which also requires a heavily modifed engine.
Just changing to solid lifters without changing the cam to one with slower opening ramps will damage the valvetrain and have no performance advantage whatsoever other than nessesate difficult valve adjustmets using GT-R style shims.
Using only an AFC with an engine with the turbo and injector capacity to make use of an over 8000 rpm rev limit is going to result in trouble.
What are you trying to accomplish? What is your budject and what sort of power output do you want to end up with?
