It will be hard to get a good idle with 50# injectors...if u search around the net you will find a pdf file on dfi tuning...i might have it somewhere I'll look later for you...

Here this link should help:
http://home.earthlink.net/~micfly/accel.htm
I would get it running a little on the rich side then put the blower on and then get right on a chassis dyno with a wideband O2 and get it tuned right
Do u have a 2 bar MAP sensor?

yep ! that and I also have the knock sensor kit installed.
The only thing I need to finish is the tcc control . No big deal though it's just a relay. I will say though that this set up might take some time to do.But it will be worth it.

Be CAREFUL with those injectors! I fired up a similar combo last year and I too didnt really know anything about DFI, I had 48lb injectors and they were wayyy to much for my combo pre-blower. I washed out my rings and thined out my oil enough to spin a few bearings and I must have hydro locked at one point because I bent a rod too.
Anyways, check for vac. leaks for your fast idle problem.
And while you are getting it going, make sure to check all your plugs freq. to make sure they are firing. and smell your oil to make sure it smells like oil, not gas. my oil smelled like a sunoco station..
