hi

built engine with stg 2 cams
lambda is 0.80
ignition at peak torque is 14 going up to 19 at higher rpm

here is the dyno
after 6000 rpm we are loosing 100 whp
what could it be?

It could be many things, as it's worse at higer rpm and hence gas flow, I'd be wondering if there was an excessive build up of exhaust pressure?
tested without an exhaust and without midpipe same thing
tested without intake same thing
weird
