Now...
If you want , to run balls out or just with a greater safety margin, go E85 and be done with it ;-) 600 to 650 cc injectors and 255 pump would cut it on moderate boost, you can always double pump and FPR later ;-0
28% - 32% more fuel , target AFR (gas based, not LAMBDA) of 11:8.1 --- 12:5.1 at WOT few more degrees of timing, more boost, bingo, knock free, cool igniting TRQ beast.
However, cold start may suck depending on where you live and how good your tuner sets up your injector latency and cold start variables, although cheaper , you will full up more ofton due to the increased flow of injector, you will be limited on where you get your fill depending on area.

I love the stuff though, it is totally addictive to run on a 'higher' boosted system. E85 on a street / track car can be hella fun

JORDO - WBo2 do not get the attention they deserve and agreed on the need for one, useful in any set up.

Sorry OP to go off on a tangant a little
