If I block the EGR without a tunner and the check eng light comes on what will it do? Am i going to hurt anything running it until I get a tunner?

Also, what is the best tunner to run without trans work? and will a canned tunner make a big difference?

I pull a 26' trailer most of the time.

LBZ mouth piece, and MBRP 5" stright pipe on the way

no it will just have the cel on and you wont know if you have any other codes.

the code will just be on but if you get rid of the dpf thr regen cycle will stay on and white smoke allllll the time

but we don't have DPF right?? so not a beg deal. and i could get away with a ppe standard ??

Yup your right. He was thinking you had the LMM.

I would actually just wait till you get a tuner. IMO the EGR blocker isnt that important. Plus if anything happend to your truck you wouldnt know because the CEL is already on
