Write both names on 2 pieces of paper and place them in a hat! Hold the hat up high in the air and have one of your kids reach into the hat and chose 1 piece of paper!
Open the paper up and there is your answer! Both are outstanding and Well Proven! Your $$$ is well spent on either one! You will not be disappointed with your choice.
No, no, that's not scientifically right: Not everyone has a hat, or children...JEEZ....
One should choose the vender located closest to them. you know the US mail has to deliver these class B mail tunes and it takes longer the farther away you are...duh.
Seriously, I picked Sean as I could buy the tuner and the custom tune, and the ported TB and the T stat all in one shop. As that's as far as I plan on going ( for now) with my Ram it just made sense to me.
Some people go tune crazy. Truth is with a stock engine and common bolt ons your only gonna get a given amount no matter who tunes it.
I'd suggest to the OP that you look at both of the vendors sites, think about your goals and pick the one you like, for whatever reason you deem valid, they both seems to have stellar reps for tuning the trucks.
