I did their Roush 427r upgrade package on my 2010 Roush in 2013, never an issue with it in almost 30,000 miles. Great guys to work with.
I can't answer that completely, you would need to call them to find out, but I would assume yes. My tune was correct first one I received. I didn't have to datalog and send them any info. I purchased their 2010 Roush 427r upgrade package which included a 2.49 pulley with a larger idler so my serpentine belt stayed the same size, as well as their tune and colder plugs. I also installed the 2011 -2014 Roush SC CAI (with some modifications)If someone gets a Lito tune, they flash the tune into the car and drive it. I was told that the car is driven to datalog in third gear from idle to 6000 @ WOT. Like Dieharder writes, Lito uses the datalog along with the addition of a wideband o2 to fine tune. Does JDM do it that way? Does JDM fine tune after the initial tune is sent? Also, does JDM leave all of the user option open such as gear, tire size, timing, etc?
Thanks
