Yes, really the largest investment to the whole setup is time. Period.
I spent a few weekends just checking out all the wiring connections and making
sure that fuel was properly routed and flowing.
Lots of setup time initially = less agony later while attempting startup/run.

All yes...

Like Ron said... idle is different with MS. I am still fine-tuning my idle...

Yes, I would have purchased the Ross rail, or Bahn Brenner one if I did
it all over again...
And injectors...I would start out with a set of used Digifant injectors or
standard Bosch injectors (Saab, Volvo... all available at a junk yard..)
It's a cheap way to get up and running. Just make sure that the injectors
are functioning properly of course!
Then, once you know the actual flow rate of injector you need, then make
the purchase for some good ones... (just the way I've been looking at it)

I tried some Bosch injectors from a Saab 900 Turbo first (24lb I think)
Now using some from a Volvo 740 Turbo (28lb)

Nope. never used motronic... from CIS-E to MS.
I went to MS all because I wanted the challenge and fun of tuning my
car myself... my rocco is my fun car anyhow, so I just made it more of
a learning experience. ;)

Let's see... to Waterfest and back (10 hours each way)
and another 1000+ miles of "spirited" driving.
I'm taking the rocco to a track event in two weeks as well... :)
