Well I made the switch to E85..I also took the blower off. We got is tuned in today and I'm very pleased. 6 back to back pull all over 1000rwhp and only 10hp max difference between the pulls. The drivability appears to be awesome so far. We also experimented with the N2MB box using the 2-step in the parking lot. It looks promising. 4k on the 2-step it made about 3lbs of boost but as soon the clutch was released it goes to 15lbs and seem to transition the weight very well. I hope to have to the track tomorrow and have some new numbers. If not it will be next Wed. I need a bigger blow-off valve. I also installed Magna-Flow mufflers(the stock look style) man this thing is so quiet. I sounds totally stock.
