I have a volvo b230A engine in my bmw compact. It has rebuilt bottom end, standard pistons etc. It has a 531 head, not modded apart from a skim, and a cometic head gasket, i think in all we took off 1.8mm. It has lh2.4, cast exhaust manifold [cant get any other in easily as its right hand drive car!], down pipes are 50mm then 63mm. The camshaft is a KL racing camshaft, its this one its 300 deg, 12.9mm lift.It has microsquirt ecu.

thats the map done recently.
Now ive been told a few things, KL racing camshafts are useless, the cast manifold isnt restricting it, the lh2.4 isnt restricting it, the exhaust isnt restricting it.
So, what do i do? the cam is it too long duration for it to make good compression? is the cam just not good, or is there something im missing?
thanks
