Default Custom Chip?

I want to get a ECM chip/calpac for an 1989 350ci / auto. Whom do you recommend I give my business too?

Car is mostly stock and has only minor mods and I have no imediate engine upgrade plans.

Mods include:
No Cats -- 2.25 straight pipes with Borla Mufflers
Cut lid with K&N filter
Ported heads and intake
21# Bosh type II
Cooling fan relay has been grounded to run while the key is "on"

*** I also want the chip modified so that it doesn't use the injector enable signal from the VATS***

Ok, thanks for all the responses, it made my choice an easy one. I'm going to go with PCM4<. I'll let you guys that responded know how it works out. Thanks for the input.

So I ordered the chip (piggy backs the stock chip) on Wenesday evening and it arrived today (Friday). Install was a piece of cake once I removed the ECM case cover. Got the changes I was looking for and the car is running great. Thanks A.A.
