Nah that pretty much sums up what we found also...for example on our stage 2 heads we use Tomei and on our stage 3 big $$ heads we use JUN. We couldn't believe how well the big JUN items woke the engine up and actually had it making more power earlier with the big port head. This is something that totally goes against the theory of what should be occurring, but boosted engines do funny things that are actually the opposite of what you would find it if was an NA.
JUN recommend running a thicker shim but this is something i strongly disagree with, the Tomei buckets are definately the way to go, as the shim should be kept around or under 3mm thickness to be safe.
But sometimes people who we do them for have their own ideas and we will advise them but at the end of the day its their money and they can spend it the way they choose to.
Risking why do we freely give away info that both you and i know cost us 1000's to discover?
We are either very generous or mad!
