GEN 1 Another huge thumbs up for JDM tuning

I was lucky enough to stumble upon a killer deal for a used roush supercharger kit a few months back. Bought it, installed it, and uploaded the Roush tune and honestly wasn't overly impressed. Definite power increase but the shifting and shift points were all off ( I ended up mainly driving in manual mode). At that point reached out to Jim Jr for a JDM tune and am really happy I did. The truck honestly feels much much quicker now, the power is really linear and constant, the shifting is worlds better (JDM is currently adjusting the shift points a smidge for around town driving and then it will be perfect)-- a little more crisp and firm then stock but not overly so, it is still a truck after all, and believe it or not my gas mileage is much better. I had planned to trade this truck in on a gen 2 soon, but have no desire for that to happen now. Really so happy with how it is running.

Picture attached because all posts are better with pics!

I have a 2012 Roush and am looking for a new tune. How much boost do you run mine is 10psi? I've been considering the JDM tune sounds like you would recommend it. Did you get multiple tunes or just performance?

Just going to jump off topic real quick how to the mud grapplers ride on the raptor? I owned the Mickey Thompson Baja claws and they didn't ride so well.

I have some 5 star tunes still N/A and they are pretty good. Though I've only heard good things about JDM also!
