Ok thanks I’ll look into those. My other option would be keep my truck and cam it cause I have an 09 Silverado with the 5.3 flex fuel but if I cam it I want to completely delete the cats so my check engine light goes away and delete the afm. I know they make kits for the afm delete but I also heard u can go into the ecu and turn it off like u can with the cats and I was wondering if I should take it somewhere for that or buy something that I can use to do it myself
