...as stated.
My lambda reads are as expected. Things richen up a bit in the upper RPM area and do it sooner over repeated runs.
I'd like to know how to be sure you're feeding enough gas.

you prob already did this - Pull your plugs and see what they look like a good a/f meter is really the way to do it

how much soot accumulates on the tail pipe, could show a car running rich. Really though the best way to tell is a/f guage. If you are running lean you'll see high manifold temps.
edit: I have no idea why I put egr there... fixed it.

Really, the best way is tuning with a wide band EGO sensor. If you can't stomach the thought of plunking down $1,500 or so for a bottom-end setup (IE Blitz A/F Analyzer) you can use one from a dyno tuning shop. But not all of them have a wide band EGO sensor, and even the tuning isn't cheap with most shops charging $100/hour ($65 minimum).
But, you really only have to use the wideband once for a major tune. If you have an EGT gauge, you can note the EGT at your desired a/f and use that as a tuning target in the future.

Plugs are clean, tailpipe isn't sooty, EGT's (tapped south of turbo, so it's only a guide) are 1000 @ cruise, 1250+ for 100mph blasts.
