any more details on your tweaks? what TB? manifold?

if you havent changed your A/F ratio, then theres no need for a chip. cams, turbo, etc.. needs re-programming to find the perfect AR. All you have done is make the engine breathe easier.

the more air you move in and out, the less restriction youll have and the stock engine will get closer to the actual specs that the engine will put out not in the OE restrictive trim.

also whats your plans with the car if your looking for power you might as well stop and by a swap....you can make good power with that motor just not worth it IMO.

hmmm its a D15B sohc vtec manifold. but now the more i think about it the more i am convinced i should rather change the head !

rather get a d16y8 head and then i would be in the business

but still will have trouble with those DOHC Vtec ,B16A... show offs
