Why aren't you running a modified 5.3L LC9 calibration?

I guess my tuner didn't opt for that? Will that work on a highly modified truck?
Right now I'm tuned for E85. My fueling is pretty good. .78 Lambda at WOT.

You really want to get involved with mine? There is nothing stock on it except the ECM, TCM, wiring, and attaching bolts.........

E-85 by nature doesnt start as nicely as gasoline does. This is why there are different grades of E-85 depending on the season. This is compounded by performance cams which decrease dynamic compression.

Hey Paul
Do you have VDF's for 2004+?
If so you will need one of mine or if John ever gets around to it 1 of his.
We have added over 20 Ethanol/FlexFuel Parameters. I have another 40 to add that really don't need to be added. They are for diagnostics.
Anyway when you see how GM does it you will understand why the factory calibrations run so well
