I don't have a logger yet so until then all I have is my gauges. These are some readings I got today with 73^ temp. outside. Tell me what you think? What looks good, and what needs work?

At Idle completely warmed up:

Idle fuel - 22psi.
Static fuel - 37psi.
Vac. - 15hg
EGT - 950^

WOT Pull @ 5psi:

Fuel -76psi.
EGT -1420^
A/F -94.5
moved up to -97.1

When we got back and idled for about 3 minutes I had 21psi. idle fp and my egt @ idle was 1025^. Engine temps were 200^ almost the whole time while not at WOT. My oil psi. gauge broke for the third time so I don't know what that was.

Stock injectors and stock internals?

I'd try to bump the a/f to the .98-.99 just in case if you are on stock internals. Looka good though :thumbsup

30lb. injectors and stock internals.

On 310cc injectors I am running around 20 psi fuel pressure at idle and roughly 53-56 psi at 5 lbs on the 20G turbo on stock internals. I have great power with an A/F between .93 to .95. Egt's approaching 1500*-1550*F. I also have a 2.5" downpipe, test pipe and 2.5" exhaust.

even though your temps are ok... somewhat... youre on the road to rebuilding a motor.

So I'm running lean? Does everything else look right?

Not lean lean... It just that with stock internals, you want more margins of safety with richer fuel.

I agree with siueclipse that I am running a little lean for stock internals. Try to keep it around .98 A/F or so just to be safe. I also run 94 or better octane fuel.
