He said it was actually going in to v-tec but it wasnt making such difference, I dont have timing tables but probably get them Monday. Can the lower compression be killing my power, I mean is not that low from stock&gt;?

no that wont kill your power like that. what wheel is in your turbo, it may be falling off. but i doubt its that, see if you can get your air/fuel and timing tables.

that is the torque graph you're looking at. HP is 250 from 5800 to 7000 and you still make over 220HP to 7800rpm. the reason its looks like that is because the HP graph reads to 500 HP and torque graph read to 250lb/ft. so the top line is torque and bottom line is HP

I dunno, you think it's going to e lower compression then 8.8:1..with 15PSI..looks about right to me.

**EDIT**

Just noticed the like 238whp at 10PSI in your sig with stock motor, you droped what, 1-1.3 compression and only have 5psi more, and you did get like 20 more whp..that's good.

With that compression, should be good for 20PSI..that's what you have lower compression for, :D

that is about what i would expect with a stock head / stock intake manifold sohc motor. You made awesome torque however.

I would be very happy with those numbers.

IMO Thats a hudge drop in torque. I would recomend a W/B next time on the dyno. Did you pull a plug after the pull?

cause if your ignition timing is pulled back to far that will rob power too.....

Stock D16z6 t3/t4b =238whp 10psi

Let me get this right, you pulled 238 WHP out of 10 psi on a stock D16? If so...CONGRATS!!!!!!!!!
Good luck with the tune and built motor!

who tuned it first of all, and secondly, i always recommend being there at the shop when they tune it, that way you can keep an eye on the tune to make sure you are actually getting what you paid for. it also helps to know the AFR's and ignition timing values that they plug in.

i cant really tell u much without knowing if it actually switched into vtec, your afrs, and ignition values.
