I am running Kooks headers on my truck with HP tuners with no issues.

What other mods do you have ?

I'm running stainless exhaust and a single turbo. 2 step launch control at 3000 rpms no cats deleted rear o2 and straight through exhaust with side exit 4" tip. Not one light on dash and truck runs great.
Sounds like the people your are dealing with don't know.what they are doing or it is some off the self low line tune device.

Atomic Performance Just remoted tuned my Cammed L86 and did a great job. I would send him a log in the morning and by that night I had a new tune. H even worked Saturday morning on a tune for me since my first fire up and log was Friday night at 8:00 pm.

And what software was used for tuning?
