I purchased the Livernois Motorsport Tuner for my 2013 Explorer Sport and installed the 93 Performance Tune on March 07 and have been very pleased with the improvements it has made. I just swapped the 93 Performance Tune out for the 93 Towing Tune and I have to say I think I like it even better for every day driving.
I ran a 0-60 about a week before tuning with an older G-Tech meter I've had for awhile and recorded a time of 5.98 sec. in stock form with about 2300 miles on the vehicle. The vehicle was in stock form with the exception of a K&N panel air filter, it's just the $40 factory replacement filter, not the full out cold air intake kit. I don't know that the panel filter really makes the vehicle much faster, but it does seem to improve the throttle response in normal every day driving. I wanted to wait till the vehicle hit 2500 miles before adding the tune, just to make sure the engine has a good break-in before changing anything. Based off my seat of the pants experiences, I could tell there was definately much better power and shifts are executed much faster. The torque management seems much better too. After enjoying the tune for a few days, I figured it was time to see what difference it made officially with the G-Tech meter, at this point I was at about 2700 miles. I made one single pass and recorded a run of 5.20 seconds. There may have been some improvement from the extra 400 miles of break-in time, but at least 95% of that improvement came from just the LMS tune, so an improvement of 0.78 seconds to 60. Both runs were performed with the vehicle in the 'Normal' drive mode with Traction Control turned off. In both cases the temperature was around 50 degrees and about 450 ft. elevation. I am at about 3200 miles now, so once I get to about 5000 miles I plan to do a couple more runs to see if I can do any better. I plan on trying to video it next time, so maybe about mid-May, hopefully I'll have a video to upload to YouTube.
So to sum things up, I definately feel it was $600 well spent and Rick at LMS was nothing but helpful with all the questions I sent him before deciding to purchase the tune. A great experience all around.
