450cc DSM injectors
SMC+
idle = 40%
1-2k = 38%
2-3K = 36%
3-4K = 35%
4-5K = 34%
5-6K = 34%
6-7K = 32%
7-8K = 32%

Umm yeah .. unless your running like over 12psi... thats running really rich.. I am also running DSM 450's and an SMC+. My settings are : idle= 40, 4k-5k= 38, 5k-6k= 37, 6k-7k= 36.. etc.. These are on my D15b7 @ 6psi and im running very rich still.. so definetly turn yours down.

a FMU? it will bring your FP way up lean it out with the vafc, it took care of my problem.

Re: My car is spuddering at high RPM (filthy frank)
Pull the gap back to about 20, That'll help out a good bit. I was running stockish 30-35, and it blew the flame out on the dyno at anything over 10 PSI and 6500 rpm.

plug gap set to .028
set ignition timing to 10 degrees
try setting fueling at -38% across
dyno with wideband to verify all is well
