Jdm engine
Jdm is pretty good, the owner used his own vehicle to develop their tunes and has successfully run it on his st for 80k miles without any issues. They have been tuning fords for a long time and get some great numbers and performance on the raptors, and mustangs. I have an sct x4 that is unmarried with a jdm tune on it if you’re interested. I had the tune built for my set up of Cvf intercooler, Cvf downpipes, intake (S&b) , and thermal 3in catback.
