Thx for the help, Matt. I almost hesitate to ask, but how d'ya go thru that many injectors?

I'll let you know how they work as soon as I put them in. I can tell you not to waste money on the Bosch (light grey/white), they do not idle properly. They were always rough during the summer but now that we are getting sub-zero temperatures, they flat-out misfire on me. They don't throw a CEL but the misfire codes are there when I scan the car. Unfortunately it cost me $500 CAD to learn this!!!

switched to the Siemens which worked well. Then went back to the Neuspeed s/w for a bit and sold the Siemens. Switched back to GIAC and got the Genesis since the Siemens aren't readily available anymore. I can't say there's much difference between the Siemens and Genesis other than the latter not needing spacers and longer bolts for the fuel rail

By bouncy idle, do you mean that the revs would move up and down for no reason until the car was properly warmed up?
If so, the Bosch 380's I have right now do exactly the same thing.
Thanks for the info.

Jeebus, what an ordeal. Thx for the help and advice.

I run the Genesis 380. Solid idle and no cold start issues.

My Genesis are supposed to come in soon. Right now the Bosch are pissing me off extremely, I have to wait like 10 minutes before I get a half decent idle in the colder temperature.
