I actually need to check with Steeda to see if they can tune for a converter as I'm not going to dyno it yet. If they can, that's my plan. If not, I'll have to do the converter and procharger at the same time so I can dyno it once. Unless TJ can chime in, I'll call them Monday to see.

Koni Yellows are adjustable. Unless you mean like a coilover setup. I put the yellows on my '14 GT and was quite happy with them.

Thanks,
