Yesterday I installed an experimental update Anthony at LMS sent me. It's based on the 4+ tune I've been running since it came out. I'm really happy to say it's a very positive update. So far I have no hard numbers but based on the good old "butt dyno" it's noticeably stronger. I have felt no loss of the good manners the car has always had. Throttle response, low end torque, and strong pull throughout the RPM range all feel noticeably improved. I'm impressed with this tune so if you are running 4+, email Anthony and get your update ASAP. You won't be sorry! I am running the 3BAR MAP and I don't know how much that has to do with what I'm feeling, but 2 BAR or 3 BAR, give this bad boy a try.
