Deleting a paccar

in all due respect because you are a very well respected member and well known. I mean no disrespect at all, The op was asking whether deletes helped or hurted. HE did not ask how to do deletes. Stating how to deletes is prohibited on here which is fine. quick google serch can ster you in right direction and most non dealer shops will get you going. with that being said, I run in souteast pa, deleting is the norm around here and there are a lot of local dot check points. cops dont check serial numbers on motors. Most guys around here delete egrs and dpf and run trouble free with no issues. Its the norm once the warranty runs out. If live in CALifornia, yeah , i wouldnt attempt

 

Just the way I interpreted OP's question. No worries.
