Not sure what happened but it looks like I haven't been on this group since 2015, I think I needed a new laptop and just forgot to bookmark the forum.
Anyways, sold my 09 LMM 3500 Dually for a 2018 Silverado dually back in 2018.
I'm sure a little more air helps, I'm not deleted but emission intact tuned with PPEI 165 hp tune and trans tuning, thanks the truck is getting to where I want it to be.
I still update on that thread, newest mod is getting finished up now from my builder. Color matched headlights with Morimoto D2S 5.0 HID projectors and LED Hi projectors in the high beams.
