seems about right honestly...
most the dynos i've seen with similar mods put out about the same output as yours

Zillion Thanks to everyone for your suggestion...
BTW, I plan to buy 70mm Ext either T1R or Greddy TiC as soon as my bank account allow me to buy one
I just would like to make sure that my Spoon N1 Ext is working well with my set up.

You should have a baseline of the car minus all the mods (i.e stock) so that you can compare. also try to go to another tuner. sometimes, it all just depends on who's tuning it. from what i know EMU is a bit hard to tune.

If it hasn't already been mentioned these numbers seem to be STD instead of SAE corrected. If so, then ignore the numbers, and just look at the percent difffeence, which looks to be over 5% at peak, which I would be very happy with. However, the bigger story is the midrange, which I think the tuner really FAILED big time!

You should be making huge gains in the midrange (~20 ft-lbs) by lowering VTEC to an optimal RPM, but it doesn't look like hte tuner moved VTEC at all, did he?

My F22C with a somewhat similar setup as yours made massive gains in the middle, with just moddest tains up top. Here is a graph showing the difference in torque from the tune alone.

BTW, I tuned a friend's '06 F22C with a setup even more like yours, and his optimal VTEC engagement was 3500 RPMs.

That was one thing, I missed it. I never get my car pulled when it was stock.

VTEC lowering to 3500rpm!!!!!???? WOW!!!

BTW, your torque look superb.
Is that because of just lowering VTEC down to 3500?

For my Dyno plot, I wasn't so sure had it been SAE corrected or not.

But, the reason that my VTEC setting and Rev limit setting were not changed because I asked my tuner not to change it yet due to I wasn't so sure either my number was looking right or not. I plan to lower my VTEC engagement during the next tune up which I may do it after I get the new 70mm Ext.

Thanks for your suggestion,

Ark
My VTEC in the graph above is set at 3900 RPMs. The other S2000 I tuned recently needed VTEC at 3500 RPMs. It's not just a matter of setting it lower. The goal is to set it "right". Every setup will have a different optimal VTEC engagement. In your case, you find that engagement point by setting it really low (~3K RPMs) and tuning it as well as you can for that engagement point, dyno it, then compare that dyno plot with the one you posted above. You'll have some RPM where the curves cross, and that will be the optimal VTEC engagement point.
