3 port boost solenoids
Guys,
I've had an Ecutek remap on my car - MY05 UK STI.
I've read about people havng these fitted, I wasn't told I needed one.
Question is, do I need one and would I benefit from having one fitted and then the map tweeked accordingly?
Secondly - the car runs approx 335/330 at present.
I was told that if I decatted fully it would probably make another 20ish bph
It currently has the PPP exhaust system fitted, is it really worth decatting for the sake of another 20bhp?
Thanks,
Shaun

short answer... YES
decats are the way 4ward, easy and relatively cheap power mod (20bhp increase is about correct). take those 3 cats off straight away and increase that burble!
i dont know anything about 3 port boost solenoids... its sumin i'd like to know about tho also.

If you already have a high flow sport cat, then I wouldnt bother decatting. (dependant also upon whether it a fleebay special sports cat or a good one).
Also make sure what is the exact setup of your current exhaust system. UK std exhaust usually have 2 cats IIRC. Has the other cat been taken out?? Is it a 3" system or 2.5 inch?
Ideally better to remap with 3 port boost solenoid on before, but now that its already mapped I would leave it until you may have done a few more mods in the future & then may require a map tweak. But if the garage you got it mapped from are willing to tweak map for small cost then might be worth a go.

you've got the prodrive sports cat which is about as good as they get, if its the STi PPP I think I'm right in saying thats the only cat you've got left which is fine so I wouldn't bother getting rid of it. the power gain from removing the sports cat is minimal and you'll have to put a cat in to pass the MOT
