Cam duration doesn't have a universal lift measurement location, sadly. Brand cam duration is based on "where this company measures from, and sets their own standard for all cams", so a bit of a subjective art to it. A bit weird, but true. Many companies will swear this way or that is the best way for measuring duration. I think lift is a more valuable measurement. JWT and Tomei are both top notch, you can't go wrong either way. Personally, I went with the JWT cams because I know and trust those guys and their long term experience working alongside Nissan / Nismo factory racing programs and trade secrets, especially regarding the VG / VQ platforms. I'm sure you'll have good results either way once the cam timing gets tuned in.
Currently, your dyno graph looks solid and a good start. Very curious to see how things look after tuning, especially over 6k rpm. Keep us posted!

Don't get me wrong,i luv my Zed to bits,but.....
every time i run over something as small as a cats eye,my back nearly breaks,and the car skips sideways.
The ol' girl has been lowered so much by the previous owner,that there is just enough room to get your fingers inbetween the arches and the tyres.
She's running on 17" wheels with low prof tyres.
I don't think the springs are shagged 'cos i bought it with a full MOT 6 weeks ago.
So if anyone knows how to make the ride a bit more comfy(oo-er missus) without making the car look silly,you would make a newby very happy-cheers!
