.84 lambda is the money target. I found that the most power on this platform is made at that target on ethanol.
Agreed though, with those mods on a stock fuel system you'll have to start blending to E60. E50 will give you a touch more headway, but there is a lot of modification you have to do in order to optimize the fuel system on these to stay in compliance with proper fuel volume and pressure delivery.
