Tuner for '12 Expy

[ExpyKen]

Hi all,

Just purchased a 23' travel trailer and am looking for some additional towing performance for our 2012 Expy KR (5.4). I reached out to Edge Performance and they indicated no tuner for our year model - anything else available? Any recommendations?

Best,

Ken

I just purchased an SCT Livewire programmer for my 07, and it didn't come with any pre-loaded tunes on it. I had to get my shop to make 2 custom tunes: one for fuel economy (normal driving) and one for performance (towing). The performance increase is noticeable, but it isn't a huge difference over stock. As for fuel economy, I think there is a slight increase, but I can't say how much yet without more testing.

To be honest, if I had it to do over again, I would save my money and not buy the programmer. I was really disappointed when I bought the Livewire and found out that I had to pay an extra $100 to SCT just to get access to make custom tunes. Yeah, it works, but it wasn't worth all the money IMHO.
