low power output on boosted h22?
I have a 94 hatchback with jdm h22.I have stock internals and valvetrain.t3/t4 ball bearing turbo boosting 8psi.Upgraded fuel system with aem rail,regulator,walbro fuel pump,rc 550 injectors,running on hondata s300.Took the car to get dybo tuned and was only able to put out 202whp and 180tq.Did a compression check and got 230 psi on all 4 cylinders.
From what ive read on different sites,a boosted h22 with stock internals should be putting out about 250 and up.Does anyone have any ideas on why the numbers were so low?Any input would be appreciated.

there could be a number of resaons but let me ask this, Do you have a fex pipe? If so sometimes they collapse and you have massive power loses.
What size DP do you have and exhaust

exhaust is holding you back by 30hp. If it drives well, check the flex pipe IM guessing your DP is 3in also?

i would suggest 3 if it's possible on your set up. take off the DP and look through the flex section to see if it has collapsed

Re: low power output on boosted h22? (siblueg)
show a picture of ur setup. it could be boost leaks, improper placement of ur dumptube, too small of an exhaust/restriction.
post up a dyno graph. that can tell alot of what is going on with ur car
