Thanks for the suggestion Tracy. I'll do that but its not the whole
problem. I cant get it to run well with any mixture setting (using manual
adjustment).
Thanks for the info Rusty. I have the stock primary injectors (52lb turbo)
in the engine block and secondary MSD injectors in the throttle body 22in.
away. The problem is unchanged if I run on either set of injectors alone.
It is doing some strange things. I have a few more ideas I want to test
then I'll post a complete problem summary.

One more suggestion. Make sure you are using minimum program width (Mode
2) when tuning in this region.

I continue to work on problems with slow RPM smoothness. No solutions
yet. I just cant get it to run in that region where the RPM is dropping but
the manifold pressure is rising. I would like to get my injectors checked.
Rusty, do you have the details of that company you sent your injectors to?
Dave Leonard
Hi Dave,
I used RC Engineering. They're a whole lot closer to you, than they are
to me :-) http://www.rceng.com/
Is this region where you close the throttle suddenly? Remind me again
how far your injectors are from the ports. If they're a long way away,
this just may not be fixable. My attempt to fix the problem will be a new
intake probably.
Cheers,
Rusty (trying to be ready to fly with Tracy's old prop next weekend)
