I would send him an e-mail and tell him your mods and he can go from there. He knows pretty much what each mod will do, and he can guess what to modify for the best general results. The way to get the best tune from him would be to get a hold of wide band o2 sensor and do some datalogging with an aldlcable and a labtop with a rs-232 serial port (9 pin male port on the side of the labtop). But if you spend that kind of money for the o2, labtop, and cable then you should probably burn your own chips yourself and save yourself some money in the long run, especially if you plan on making more mods or an engine swap down the road. Plus you learn a lot about the workings of your tbi. But if all of this seems too daunting, the easiest and cheapest way to go would be to just tell him your mods and let him send you an off the shelf prom.
