guys just need a tad of assistance here as i want to get this right

my99 uk turbo+ simtek. iv just binned my avcr (binned all the stock boost control stuff apart from map sensor moons ago too) the apexi had all 3 ports on the boost circuit hooked up + the apexi boost pressure sensor too. iv got a hybrid 3 port im going to replace it with...soo....

1) should i connect it all back up how it was with the apexi BCS? + do i need a restrictor pill back in there somewhere? mapper said a .6mm on a 2 port will compliment the simtek really well, but i dont just wana run 2 ports..i want 3.

2) now the boost pressure sensors gone, what do i need to replace it with? a stock one or aftermarket (presuming i need one!)

3) map sensor - iv no idea where this vac was hooked up to, where should it go back? just anywhere on the manifold?

1) Why do you want 3 ports over 2?

2) The MAP sensor is the boost pressure sensor (and vacuum)

3) The vacuum line for the MAP sensor goes on the inlet manifold, anywhere after the throttle body, preferably not T-pieced with anything else.

1 isnt 3 supposed to give better control over pressures then 2? surly with an ecu that can do boost control thats a no brainer?
2 so now iv scrapped the apexi boost pressure sensor, i dont need another? just the map sensor, plumbed to the inlet

1) Yes connect like the Apexi. No restrictor no.. 3port better than 2port.
2) You still have the pressure (map) sensor original one on the car? or 3bar if it has been replaced when the simtek was installed?
3) you just need to remove the apexi one and swap the 3ports over.. no need to refit map sensor it must be there already as the simtek will be using it.
