He needs someone to tweak the engine ECU maps, to work with his mods.

This happened to Car & Driver a few years ago:
They dyno'd a stock Subaru WRX, then added a CAI (Cold Air Intake) and dyno'd again; Gained a couple HP.
They re-installed the stock intake, then put in a low-restriction exhaust system. Dyno showed a couple more HP that way.
Last, they bolted BOTH the CAI and exhaust on at the same time, and actually LOST HP over stock when dyno'd.
They ended up spending almost $1000 for an ECU tune to make all the components 'play well together'.

To answer the OP's question, I think he should look locally at first; perhaps ask of a local Civic club or organization...Sometimes a local auto parts store (or Speed Shop) can refer folks to this type of service. (I know who to ask in the NJ area, but that's all)
