Like rissky I've had a very good experience with LMS. I started with STG 2, and STG 3. Then they provided me STG 4. Then they supplied me with 4+ which I happily ran for a couple of years. Some time ago I asked for and received a 91 octane and a 93 octane version of 4+ so I wouldn't have to switch to another stage just because I had to travel to an octane deprived part of the country. Recently I asked for a 170 degree T-Stat versions and they once again were happy and courteous to provide for my tune needs. A couple of weeks ago I decided to switch to the 3 BAR MAP sensor, for some reason there were some difficulties getting me hooked up with a working 3BAR tune. Anthony kept working with me patiently till they could figure out the problem. I spent my money with LMS probably 3 years ago and they are still giving me the same stellar service I would expect if I just bought my tune a month ago. The tunes are honed on shop vehicles and fully tested before releasing to customers so I never had to go through a logging/adjusting phase. I feel secure in LMS's reputation for a dependable, safe, and strong tune. All in all they have my highest recommendation!
