my set up
Jun 3's valve train done too
got a obd1 ecu to rev up to 9000rpm
have a apexi v-tec controller to tune fuel
and a FPR
also AEM cold air intake

tuned dynoed at 163!

would anyone know the reason im not making power or have any suggestions?
thanks

in an ITR?

 

even without itr those numbers are SO low. you should be at least 180-185whp.

 

yes on my ITR

 

your tuner must suck. come down to socal and go to IB and let them give it a shot

 

worse than your spoon cams...

 

my tuner is very good and he said it was the valves cause he said he heard a ticking so i had him readjust them but havent gotend it tuned or dynoed again?
feels better and stronger
he said the valves were different number one was 5 another 6 another 7
cause heard the ticking too so after he readjusted them it feels stronger but i dont know the numbers yet, got to go back and tune it again

 

yes

 

bet on the ECU.

 

What header do you have? You will lose power with that setup and stock ex. manifold.

 

stock header and ex

 

JUN 3's will make that ticking sound when it's cold. but once it's warm, it should sound like stock.

 

jun3's love to breathe...if your header/exhaust isn't really flowing then you're losing lots of power. i would bet 15-20whp block with stock header/exhaust.

ot: nice to see you're still around, Gary

 

p28 ecu

 

when v-tec hits i loose power on the dyno and on the street
around 20whp

can valves make you loose hp ?
but know i got them adjusted again and they were not adjusted right from the begging before the tuning know i got them adjusted would there be anything else that would make me loose power besides flows header exhaust
and it feels strong but its not still making the power it should be
whats the deal yall?

do you have the dyno chart you can post? Try putting the stock ecu back in the car, i did 185 un tuned right after i dropped mine in. Valves shouldnt make much difference, unless your valve lash is really loose.

 

>>>when v-tec hits i loose power on the dyno and on the street
around 20whp<<<


that is definately your stock header/exhaust choking the jun3's...CHANGE THEM

As posted above, the valves will make noise when the car is cold, but it will/should go way once the car warms up. Also, you NEED a header. If you dont want an exhaust, its cool, but you NEED a header, that is a main thing holding you back. If you put that much $$$$ on your setup, you should spend another ~$500 and get a header. with those cams and a stock header, when vtec engages, it feels like you hit a brick wall (trust me i know )

Also, what is you timing set at?? Have you touched your timing, or are you letting the p28 ecu take care of that for you?? Check your timing, make sure its not retarded or something.

 

when is your vtec engagement???
what program on the p28???
if its just the stock p28 then that will be the cause

i have JUNs too
i made 198hp and 130tq w/ a missfiring igniter
*tuned by DSR

those are some nice numbers

 

Talk about doing mods backward, changing cams before H/E!!

If I am you, I would go change the at least the header first before going back on dyno to tune it again.

 

What kind of dyno is it?

 

It is your stock manifold

The last time I saw aggressive cams installed in with the stock manifold, the car would barely run. Dyno'd 165whp or below. There is no other reason for your car to be putting out that little power. It's not the cams. It's not the valves. It's not the dyno.

It is your stock manifold

Go buy a JDM-sized header, beat yourself over the head with it, and install it on your car. Retune as needed.

 

HAHAHAHAHAHAHAHAHAHAHAHA
