Testing E85. Do you?

There are a couple theory's behind that.

-Gm didnt wire the car with heavy enough fuel pump wiring so they compensate for the weak pump in the tune (I don't honestly see this one considering people regularly add 50+ horsepower without the pump sagging)
-The bosch regulator isnt perfectly linear

Cool. Thanks for the insight.

I have tried sloped and flat line with my setup. Much better results with it flatlined *shrugs*

LOL

Thanks just ordered mine

Great! Be sure to post your results.
