keep giving Diablo your feedback as i know the 4th gen pcm's are alot tougher nut to crack. and yes, you can always use higher octane with whatever tune you choose, just don't go lower. I was in same boat with my predator when I first got it years ago for my 05.. I think the canned tune is runnin fat from the gitgo which may seem slower when startin off... if you can monitor a/f ratio, see if it's running fat at idle and part throttle..
