Finally had it intalled. I had been looking for somewhere locally to do it that was dependable and found a shop about 30min away in Longview. Haven't really laid into it yet, but will soon. I am heading to Austin to Uprev on the 23rd to get on the dyno so it will be good to already have this mod done. I will let you know the results once it's tuned. Oh yeah my truck is an '07 KC Big Tow with 14in magnaflow muffler swap.
