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.
