*** dyno = junk. Get it on a real dyno and tune it. Keep in mind that you should follow the other posters advice and do a valve lash adjustment as well. Also keep in mind a crappy PnP will kill power as well. You don't indicate what you did when you pulled the motor.

 

The port and polish was done with the old setup, I made 192 whp on a mustang dyno w/ the stage 1 cams(so that is not causing the power loss), I put the engine in the prelude (it had been in my accord) with the s2 intake mani and type s intake. I drove the car for a few weeks, THEN put in the stage 2 cams and nothing else, drove for 2 weeks keeping under 4k. Once going through the full rpm I felt no real power, i can DEFINATELY tell you that it was less powerful than the stage 1 cams. I DID do a valve adjustment. Any other ideas?

 

I guess I should clear something up since I have gotten numerous PMs from people telling me i need to use a real dyno and not a "butt dyno"

Uberdata is similar to Hondata, my car was tuned with it using a WIDEBAND o2 sensor and realtime software on a laptop hooked up to the ecu. I tuned it for 3 hours until the a/f ratio was looking VERY good across the entire RPM range.

 

Its possible you may be suffering from that Skunk2 manifold. Switch your manifold back to the old, then try and retune. Also have you checked your plugs and all that happy crap ?

Im not saying the skunk2 manifold is ****, i just havent seen all that fantastic of results with it. I still need to tune mine as well, but i gotta save some cash for awhile for other stuff.
