@LucidMomentum, I'm working on a new tune, and new maps to go with it. I call it EconoSport because it gets better mileage, while still making good power on WOT. Just drove 70 miles to Wilsonville and back testing it out on a full tank of gas. It's still building up too much pressure in the lower, (>3500) RPM's. It's also still a bit twitchy when I suddenly let off the throttle. It pulls much better at 55 MPH in 4th gear though. Still nowhere near as quick as 3rd gear though. My earlier maps had the zero, (Half boost) point as low as 2000 RPM's. I've found it needs to be at least 3500, or it over-boosts. It seems my car can't handle manifold pressure over 14 PSI under 3500 RPM's. Over 3500 RPM's it goes like a bat out of hell though. EconoSport 3, the top one, is what I just used to drive 70 miles on, and EconoSport 4 is the bottom pic, which I'll try out tomorrow and see if it still over-boosts. I did get 34.5 MPG average on the trip, and I had to give it some heavy throttle occasionally to test for over-boost. Although these look similar, the scaling is different. On EconoSport 3 I started from the bottom and added 10, then 11, then 12 and etc. on up to 100. This gave me a zero point as low as 2875. On EconoSport 4 I just added 10 till i got to 3750 RPM's, then added 25 from there on up.
