My homefry Nick has his B20Vtec running off a chipped P28.  He runs low 13s on steet tires in a CRX.  I'd say that is an acceptable solution.
The tune he made himself was made with Crome (a free romeditor available on PGMFI) with a lot of trial and error.  It took him several hours of driving around to get it running decent.  When I get my wideband, we're going to go and retune it to a perfect AFR.
Myself or James (hardlowrdranger) can both hook you up with a P28 chipped that has a tune that will run the car pretty-very well.  James is a much better tuner than me, and I have a feeling he'd be able to give you a better chip.
