Alright guys, Im new to all this. Ive got a 2010 6.4 with 4" cat/dpf delete, with the SCT Livewire extreme 9625or. Been runnin the 4 tunes with the programmer, but I want some custom tunes. I know river city diesel offers good ones and Innovative Diesel does as well from what Ive read, but I aint found any newer posts just older ones. Lookin for up-to-date info... So from y'alls experience what do y'all suggest? Im lookin for somethin smooth and not hard on my truck but gives me somethin to play with now and then, and smoke a little too. Oh and this is my first progammer so I am clueless
