I think 1.1 and hotter may be a slight difference in power. It is the hotter and the hotter lag fix that are the same in boost . Really nice to have the hidden diagnostic maps as well. Although, JB has the most problem free tune on the market in my opinion. Still nice to know that if there was a hiccup of some sort Terry can find out what it is with the diagnostic maps. Nice review, and i'm jealous you got it before me.
