My dad has a 08 lmm ccsb that is highly bone stock, has a dpf back banks kit (dont ask) biggest waste of 600 ive seen but whatever it got rid of the megaphone, my dad bought a dpf delete pipe and i was wondering what everyone would do for a tune, he doesnt want a dsp5 switch in the cab so let me know what you would do? i have pulled stock tune and am going to send it somewhere to probably get a dsp5 tune. just wondering if their is anything else you would do at the same time
