King is spot on, with our LT1 we weren't able to run much of any boost with full E85. If i remember correctly it was like a bit over 450 RWHP when we hit the limit. So while we still use the stock LT1 high side, all fueling over the 450 (to the current 728 RWHP) is handled by the port injection system.
