vtec at 4000 looks too low for me as a DD. 5000 would be better isn't it?

it will be throttle dependent.. i.e vtec would only engage at 100% throttle position at 4000 pm so you won't be in vtec while just driving on the highway...the tuner will phase it in so that at higher rpms, it'll take less throttle engagement to engage vtec
oh one more thing, so is 8600rpm is the highest rev limit i can go with AEM EMS?

great that's what im concerning about. thanks for all the suggestions man oh one more thing, so is 8600rpm is the highest rev limit i can go with AEM EMS?
oh one more thing, so is 8600rpm is the highest rev limit i can go with AEM EMS?Im not sure how high you should go; most goto 8500. I only went to 8000 (stock).
Sorry i can't help you with that one

the AEM EMS will let you go high as you want

On the ap2 power dies off after 8500 max. Sometimes earlier, even with mods. No need to go any higher.

Now to give you some perspective on HP numbers... I have a pretty well built NA motor and the tuner I work with has tuned hundreds of S2000s, more than probably anyone in the country. A stock AP2 on his dyno is 237 hp to the hubs. The highest he has seen without ITBs is 270. My car was about 264 with a high flow cat. This is with bumped compression, head work, cam gears, etc, basically everything on the top end changed. So as you see making 25 HP is a lot of work.

I have mine at 3200 RPMs and 40% throttle and it doesn't impact drivability at all. Just because you can do something in the software doesn't mean you can in reality. What I mean by that is you don't want VTEC to come in late in throttle position at low RPMs and high loads because even with the stock motor you will be a lot more likely to pre-detonate or "ping". With the AP2 cams you can set VTEC around 4200 RPMs and you will see a nice curve.

Out of curiosity, who is your tuner?
I left the NA realm a while ago so I've been out of touch for a while, just remember the basics.

8500 is most you want to go for the sake of longevity.
However, in HP or TQ terms if you did the calculations you would probably want to go higher. You can't just look at the TQ curve. You can look at the HP curve to get a good estimate.
What you really want to do is look at effective wheel TQ. So if you are making 150 TQ at 6000 RPMs in second gear versus 120 TQ at 8500 RPMs in 1st gear the numbers are:
1st gear @ 8500 RPMs: 376 effective wheel TQ
2nd gear @ 6000 RPMs: 307 effective wheel TQ
Based on 3.133 1st gear and 2.056 2nd gear.
You want to stay in 1st as long as the effective wheel TQ is greater than if you shifted to second which it is in this case. You can't get this from a dyno alone. Dyno's tell you wheel TQ at a 1:1 only.
One thing about HP is you can't feel it, but mathematically it's the more important number.

wrong forum...
but, when I was NA, I had t1r 70mm with test pipe, j's header, K&N fipk, and was tuned with the emanage ultimate. On my tuner's dyno, peak whp on stock ap2 is 220whp. With the mods I had about a peak whp figure of 247 or so, and ran a 16:1 AFR at 5000-6000 rpm
Tuned, I had 250whp of peak power. So I picked up 30whp from those mods.
But the real difference was in the midrange, where I picked up 5-25 ft lbs of torque between 4000-6000 rpm.
