[QUOTE="Canuck714, post: 1510689, member: 6707"] Since this is a thread from 2018 that I accidentally revived... SORRY Guys I will jump on that comment, and give you something to think about Anthony. I have a very well mannered, easy to drive JDM tune on my Roush that is my daily driver. 117,000 miles and counting, SC since day 1 and still kicking ass!! I have a friend that has a business of building high end turbo cars and has some of the fastest LS based Corvettes here in south Texas. They had been giving me a hard time about what wheel HP my truck made one time, and they wanted to see it for themselves. It put down 507HP at the tire on a 37. Pretty stout I took the JDM "best guess" tune out, and laid the stock Roush back in so he could play around. He was able to make 20hp over the JDM in the middle of the curve and 7 more at peak. Pretty impressive I have to say. Guess what tune I run??? The JDM... The custom tune is miserable on the street. Fantastic if we are WFO all the time but it has terrible driveability. The tuner even agreed that he would need a day of driving around data logging it to get it anywhere as good as the JDM tune. The changes JDM made to the transmission was not easily duplicated by the other tuner. So while it is true you can make more with a custom tune, that doesn't necessarily make it better than a well sorted tune from JDM or others. Some people dont have access to a good tuner, or dont want to spend a day to try and get 5hp.. Its a 6000lb truck, you wont notice... [/QUOTE]
