my ignition timing is fine doe????

not really well depends who's doing it i guess, My friend has it happen to him on his saxo and it was his cam timing. The same principle is there. Where abouts are you?

Would this have anything to do with the flywheel being worn out????my mate had the same problem in his dc2 and i think it was due to his flywheel being totally worn out....

only got a new competition clutch fitted few weeks ago bedded in correctly an all
flywheel was fine
 
I had the same problem on my EK9 B16B and it ended up my cold air feed was too small. If you have a cold air feed get a bigger one. I had an Integra Airbox with a Hamp filter with a 60mm cold air feed and it made 170bhp on the rollers then changed it to a Top Fuel Induction Kit with a 90mm cold air feed and it made 192bhp. Mapped it and it made 206bhp! :) I also have a 2.5 exhaust system, spoon 4-2-1 and a de-cat tho!

well bit off an update ....

dizzy- rebuilt
ignition timing- checked and is spot on
cam timing - checked and is spot on
calipers- all checked and ar spot on
compression- checked and is spot on
leak down test- checked and is spot on
car was serviced and engine was flushed

still no engine check lights ......
but the problem is mainly upon vtec still
so i had the head lifted off friday and eveyting is fine in the head
and no signs off any damage in the cylinders

so now i have a mates car that he is breakin so i will be swappin over all sensors which ar workin perfect so this should eliminate electronic fault

Yes it would....

for wheel horse power yea, but on spin down would it not adjust the flywheel as loss to wheels?

id like to know what ecu? as in even if running crap it till shouldnt drop out of vtec, i know the ek9 is a late enough engaugement ? 171 is ok enough for an ek9 though? what torque did it make... i know of a few that made that... its hard to get an ek9 to 185... plus thats ps so its really only about 180... ur only 9 off so its not the worst dyno i have seen... can u post the afr? too rich or lean could effect the 9 bhp or so.....

can u post all the results?

Dyno Dynamics are a eddy current load bearing dyno not a inertia type Dyno so you don't need to let the Dyno spin down to calculate whp, it calculates everything on the power run.
 
no way of telling if brakes or gear oil etc effect it then?

learn something new everyday.....
