There will be 8 by next week.
E85 burns cooler, is easier on your engine and makes more hp then gasoline and methanol. It comes out of the pump so there is no mixing, no pumps, no nozzles or meth controllers. Meth injection makes your car less reliable because it introduces many more failure points.
Its available to me. If it is available to you and you choose not to use it you are an idiot. If you do not have access to E85 then meth injection is a good alternative.
You must not be paying attention. He is running out of fuel. +7 is todays number. It won't be the final number with some more fuel upgrades.
I am seeing IDC of 105% on 80# injectors and a 2.9" pulley but I can still get my Commanded AFR in PE. If I go with a smaller pulley I will need more fuel.

i know of a fucked up trick to get your idc's lower.
also. you want more power. drop your stoich to 10.43. a very wise master of the fuel told me this

Does it involve keeping my right foot off the pedal? I am not interested. jk
I am all ears.
10.43 Stoich?
That would require a lot of other changes to my tune that I am not smart enough to make.
Or do you mean 10.43 afr (converted to gasoline lambda) in PE?
This is something that have been confusing me.
According to this the Max Rich Power for E85 is .7143 lambda. Multiplied by 14.7 (gasoline reference) that is 10.5.
Typically we tune gasoline for the Max Power rich of .8503 lambda. Muliplied by 14.7 that is 12.5.
SO...shouldn't the E85 converts be aiming for 10.5 (gasoline converted) afr?

i run well below that on wot runs.
setting it to 10.4 works peachy. gas mileage suffers severely.
all that is required to make the change is more maf work. like you have done before. not that difficult really
