I’ve been gone a while. I never did get that challenger 6 speed I was dreaming of.

got the trx instead of a raptor. And since it is what it is, trying to keep the stock tune for a bit. But looking for bits and pieces to add a little power here and there.

everyone talks about the incognito pulley, but what about the ATI damper pulley that also adds boost? So you get the benefit of a crank damper and a bump in psi?

second is headers. Since the trx comes with the log manifold, I think the old 392 manifold would be an upgrade if it fit the frame. Let alone the ARH stuff.

does anyone know if the ARH headers would be safe on a stock tune?

and then because I’m greedy: would the headers and the equivalent boost from the pulley change; run safely on a stock tune?

I would say no, you need a tune to keep the AFR safe.

Yea I was wondering if there wasn’t enough flexibility.

I found a copy of the 2021 trx tune via hptuner.

I need to get a copy of the 202x Hellcat tube and compare them. See what changes they made for things like the intake and the exhaust.

I mean if they are the same except scaling for any map due to different intake assemblies… then technically there should be enough on the table at least for headers. The arh headers for the trx are short. So there isn’t a lot of changing.

but they sound sooooo nice. Yea. I’m that guy. I’d love to do them and keep the stock exhaust.
