As far as tuning and performance wise??? 06 model in general?

 

I do not believe so. You may see different gains running the E-85 fuel, but on pump gas I do not believe so... although it is a new technology so 100% fact is hard to come by with these motors.

 

Flex fuel you will get less miles per gallon, the positive is the E85 is a higher octane and burns much cleaner. Bad thing is E85 in some states is really hard to come by. I am in oklahoma city, and for sure only know of one place and it's in the middle of down town and it cost jsut as much as gas but you get about 3/4(guesstimate) of the mileage out of it.

 

I remember seeing somewhere that GM uses bigger injectors on the E85 motors, so that might help some down the road if you get into tuning the PCM and other mods. More fuel =

 

yep they have 38# injectors and a bigger fuel pump....

 

now why couldn't you answer that in my post lol hahhahaaa

 

Yup... They do come with bigger injectors not sure about the fuel pump.

 

Yea, there's only 1 station in Georgia and it's in Albany, which has a population ~500 lol.
