This isn't the busiest of Supra sites, no. I've been pretty busy and haven't had a chance to really read through it but I've been meaning to make some time to go through your post and see what I can come up with.
I'll look it all over tomorrow (it's very late here now) and let you know if I can think of anything that's missing. One issue that comes up from time to time it the CPS being clocked 180? off (refer to the FAQ thread on timing to make sure that one is right). And no, there is not proper polarity for the RC injectors, just a simple coil in there so nothing to worry about unless they're not wired in the proper order.
