Updated and went straight to level 4. After some city traffic driving in T/H for relearn I found a straight stretch and nailed it and holy ****. The pedal response is instant. Lot's-o-smoke !There is so much more boost there is almost zero lag. My rear tires are crying. Can't seem to get traction through first and second gear. EGT hit 1320 for a sec or 2 but came back down quick. Found a few willing to play and nothing was even close. This thing takes off like a rocket. On the interstate at 70 mph just barely touch the pedal and it is gone. Hit 100 really quick. Can't wait to get to the track and see what the new tune does. I have no doubt high 13's if the tranny holds up. I will get a chance to test the mileage tune this weekend on a trip to houston and back. I normally average 16 MPG the way I drive so we will see. I can only hope that the other levels are as improved as the extreme. Can't wait to tow my 38' TT with the tow tune. Thanks Buck! For what I paid for the EVO upon release I got one heck of a deal on a great lil programmer and great customer support as promised. Just sold a unit this afternoon for you guys after a test ride for one of my friends. I will let you guys know what I find after this weekend. Gonna try level 3 in the morning and work my way down. Yea...I am bass ackwards like that.
