yes Its not a good result for the dev4 and race series extractors when even with a unichip it won't equal a dev3hl cam with pacies! on the same dyno same operator and all that.
There must be a reason behind it the engine seems OK on all the basic fuel ign compression etc. I don't know about the cam timing though! maybe the pattern in the attached comparison will tell you more.
Attached is some JMM modded cars up here in Sydney all on Spiros dyno.
