I have a Intense 3.2 and 3.1 3.0 pulley ready to go on and i know tuning will effect which size 2.8 or lower is the goal but just curious with my setup now which pulley would you guys start off thanks!!!

I say start with the biggest you have and scan, scan, scan and take it easy until you see what data says and go from there.

Start big and work your way smaller. Pull lots of timing, and then start dropping pulley sizes and see where you end up.

Who and what are you using to tune it?

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!

Mind explaining that? Special Boost Controller? Lol...With that setup, I agree with GMR. You should have no trouble running a 2.8 if not smaller.

Yes, get straight to it....Start with the 2.8 and stock timing tables. You won't be able to get E85 to knock with that setup...and if it does there is a mechanical issue. With E85 it's best to monitor AFR...not KR because E85 prevents knock so well.
08-23-2014
Good point. Monitoring your AFRs may work just as well.
by adding more boost, I simply mean dropping pulley sizes further

Greg... I still need to swing up to C-Bus to check out your turbo parts for sale!

Greg again you lead to the promise land dyno tune after i get the E85 tune in just need to grab a new valve body and a 7/8's trans wont hold to much longer with that power im making
