Not even a chub, but a full out rock hard boner. Curious what this will do for just something stock?

The problem with the current VVEL settings and FI is that there is high overlap (i.e. intake and exhaust valves open at same time) such that the force inducted intake charge can blow right through the cylinder. By changing the timing and reducing the overlap you can capture more of that FI in the cylinder and make more power.

Maybe now we can finally start making the big power of the 350Z engines at similar boost levels

So for us FI guys this means more power at same boost level or better drivability? I like the idea of more power but I think we're already at the safe zone these motors can handle. Anymore power n I think we'll be risking the longevity of the motor or it blowing up no?

Interested to see whats done...

Are they any gains to be made with no cams and just a tune? Just finished my N/A Tune with Randy from UpRev. If this is just in test phase then I'll wait till I get my F.I. LTH before I get another E-tune.

If there are significant gains to be made. Then I'm pulling the trigger on the JUN cams like now.

Lets see what happens
