Problem with my BCS ??
 

After almost 2 months I think I've finally got to the bottom of my slight boost control issue in 5 th and 6th it flutters and drops off boost after changing the coil pack plugs all vac lines and intake pipe I decided to give the boost control selonoid a clean with intake cleaner took it for a run and was fine but the next day had the same problem cleaned the BCS again and it drove fine again so I need a new BCS but should I fit a 3 port or just go with another oem 2 port will a 3 port require a remap ?

Remapp/ tweek for a 3

Would I be better off with a 3 port I've heard there more accurate ?

3 ports can control boost better but do require mapping in. Second hand good 2 port will be a quicker fix and more than up to the job at low levels of tune.
