Cool dude I got in contact with right person, he is trying to set me up with the correct installer. I might have to buy the DIY kit as my local installer has not answered any calls or email in the past few months. The people who were telling me they could not tune the truck are actually not affiliated with Yotawerx and are with a different tuner. Yotawerx says there is no issues with tuning with long tube headersI'm have the 2 downstream cats remaining in the midpipe, but both upstreams got deleted when I installed the LT headers. I'm in good 'ol emissions free Missouri. You can also reach them via email: yotawerxtuning@gmail.com
