This fact alone is why a normal stage 1 car will only make around 250bhp. (i.e. we are upping boost from approx 10psi to 15psi for an extra 40 bhp) To expect any more than that increase from just a 5psi increase is unrealistic.
When mapped correctly it is possible to make closer to 300bhp on a stage 1 setup.
Fair enough.
But i expect from a trusted compagny to give realistic output figures then.
Not stating 280 bhp when getting an almost standard 224 bhp.
Al this assuming that all the rest of the engine is ok of course !!
But for the moment i can't find anything wrong. And AFR seems ok.
When checking the ignition i indeed saw that advance never got earlier than idle ( 8° i think )
I will check compression rate next , but nothing makes me feel this won't be ok.
But measuring is knowing.
