I went with the 200's due to my 60-1 turbo and the rest of my mods and even a recommendation from Comp. I do not however want a rough idle if I can help it. Comp says it is not that rough.
I have an EPROM ECU with inj. compensation. Will base fuel pressure or base timing help smooth the idle? Anyone have any tips? Thanks, mark

Rise the idle and tune. Nothing really more you can do. If you want to get really into it, pull the motor and get adjustable cam gears and dgree the cams then tune. That will be you best bet but it takes alot of time and some special tools.
 
I had Jeff O raise the idle on my eprom to 900 rpm and it is just as smooth as stock. I also had to lean idle jsut a tad but nothing major and most people cant even tell that I have them installed.
 
Yea same here I have the 100s and it idles just like stock at 800 rpm. Have not heard of anyone here having a problem with comps Idle. If you have a problem with a bouncing Idle or other wise your tps may be gone or you are just running to rich.
 
Well the 200's idle like stock at 900RPM. Lost 4"of vacuum max. Smooth broad power range. Almost a dissapointment that the are so mild and would have liked more power but I am running a stock block with 110k miles on it. I do have a 6 bolt to rebuild that had 86K miles on it's clock. My friend said going from a tired stock motorto a 9:1 compression really made the power. That's next!! Thanks for the help and encouragement. Mark
