I think I was getting 1.6-1.8 negative corrections - I have everything from the list except the IC, got the plugs from Whoosh a few weeks ago. The dizzy tune was ok in the morning when I was headed home from work (About 49 degrees F, really cold for here) but in the afternoon on the way to the office it was 85f and my IAT's quickly hit 105 under load. My IC is on order so I'll leave the dizzy tune off until then. I did notice that one morning to another the dizzy feels much smoother, but the Stratified feels *much* more powerful than the dizzy s2. It might just be that the dizzy has to spend more time learning whereas the stratified never hits any corrections or whatever. No idea, but after I get my IC I'll do my datalogging. I could *really* feel it when the dizzy pulled power, the car fell flat on it's face and I pulled over and reflashed back to my strat tune. Not knocking the tune, it said right on the page "requires an intercooler upgrade", I just figured it wouldn't be an issue when I almost always drive at less than 5/10ths rarely boosting. It was at part throttle where it got grumpiest.
