Strange enough the non vtec cams are making very good power, until the vtec cam hits in and makes the infamous "greddy vtec dip" ?
perhaps this is solvable with a better tune or change the vtec point to 6500-7000rpm?

When I talked to Taun at P-Tuning, he said the first thing he was going to do was to Raise Vtec, are you saying he won't be able to do this on an Ap2 with Emanage? He seems to know what he is talking about

In order to change the VTEC engagement point with this turbo kit, you need to change some wires in the harness. The ultimate CAN change vtec, it's just that the harness isn't wired for it. It's very simple to do

I don't quite understand this comment.
Are you saying this dyno chart shows a turbo does keep the stock s2k power curve?
I beg to differ, the torque is great up to VTEC (unlike stock) where it actually dips to redline (unlike stock).

The post VTEC dip isn't just a Greddy issue, ALL log manifolds seem to have a post VTEC dip in power and torque. On the other hand, tubular manifolds and superchargers tend to need VTEC set lower, not higher.
