Thread: Which Pulley should i start on E85?

With that setup, I agree with GMR. You should have no trouble running a 2.8 if not smaller. However, just as stated, start with low timing and see how it does. If it were me, I would start with the 2.8, and the stock timing tables. Do some gradual part throttle pulls. First watch KR, while checking on your AFRs as well.. If everything seems okay, give it more throttle, and repeat.. If you can get to full on WOT pulls with no KR on the 2.8, I personally wouldn't add timing. I would keep the stock timing tables and add more boost. That has worked best for my E85 setup.

let me know if you have any specific questions about the tune. I've been playing with my E85 setup quite a bit

Good luck!
