I just had my car on an AWD Mustang Dyno with the newest LMS tune. I have the most current version: 93 V11, 3-bar, gapped plugs, Windstorm CAI, 160 thermostat. I also have Magnaflow cat-back. I've had LMS tune since about 1,000 miles. Car currently has 45,000 miles. *I've been extremely happy with LMS.* But I keep getting missed shifts between 2-3 (more often than not) and there's hesitation (minor sputtering) under WOT at highway speeds. The car is in perfect condition, very well maintained, I've overfilled (just barely) the transmission as advised, injectors been cleaned, etc. Car has a brand new PTU installed in 2017 under warranty, and all maintenance done more often then recommended. I don't know if it's the tune or the car... BUT, we're going to find out. I'm going to install the canned Gearhead tune later this week. Same exact mods I have now but switching from LMS to Gearhead. I'm going to run the car on the same dyno after the Gearhead install and report back. And I'm going to see if the shifting issues go away. Results on the Mustang Dyno for my 2014 SHO with PP with the mods listed above are: 333WHP & 390 WTQ Gearhead = ....??? stay tuned.
