So I decided to purchase the 3 bar map sensor, 160* thermostat, new motorcraft plugs, and had Anthony @ LMS write me a 4+X tune for my 2011 SHO non PP. I got all the new parts put in, and started the download of the new tune.... 80%.....90%......99%......100%!!! I backed out of my driveway to go do a quick test hit (in Mexico) and MAN... what a difference from the stage 4+ I was running before. I brake boosted up to 2000 rpm and let it fly.... had a tough time grabbing traction through first gear.... THEN came 2nd gear, and all 4 tires let loose again! What a great feeling. I only have an 1/8th of a mile track around me, so I will be taking it to see if I can improve my time hopefully within the next week or so. I am also daily driving with this tune to see if it is a safe, and reliable tune for the streets as well. One thing I have noticed is even if I am only using 40-50% throttle from a dig, it still chirps 2nd gear. Kinda cool if you ask me. I'm sure that will tone down a bit after it "learns" how I drive. I will also keep an eye on MPG change from the 4+ to the 4+X. And just to sing the praises of Anthony at LMS.... he has been amazing in his wealth of knowledge of our 3.5L ecoboost motors. He has taken a lot of time out of his day multiple times, to explain things to me, and discuss future options, and letting me know what power gains I should expect. He knows the science behind the motors, and knows what make them tick. If you have any questions about his tunes, feel free to call him. He will take the time to explain until you understand. Thank you Anthony.
