port and polish problem

[torinoredcivic]

evrything is finally completed the d15 vtec is in the si gearbox is in.i just did port and polish on my head and shaved it a bit but the car seemed to react oppositely to it.the guy who did it told me that it needs at least 1500 to 2000 kms to work correctly and i have found it to be true.why is that and what i should i do to increase the fuel on my car with the stock p08 ecu because it seems to run a bit lean.
thanks for this great board

hondata would be the best way to go, but an adjustable fuel pressure regulator will probably get the job done.

alot of people think u can just slap on a "port and polished head" with no other mods.more air means u also need more fuel.

Think about it...That engine was stock. It`s no longer like that. Especially when you did some work to the Cyl.Head. It`s out of the Specs at this moment. When you regrind or milled the Cyl.Head the times retards. That` why you need a cam gear or sprocket. Also it would be better for you if you could get an Injector Air/Fuel monitor (not gauge). That monitor would tell you if need bigger injectors, fuel or air. for the Inj. A/F monitor go to:

Try a couple hundred dollars, I've heard them things are close to $1000 or more, that's why dyno shops can afford'em.

I was talking about the Narrow Band. They run for like a $100.00. and it`s really easy to install,only 4 wires.
