2011 duramax alterations
 

Thinking about deleting dpf and running a straight exhaust with k@n filter has any one done this will it make truck act up

Without a tuned ecm or proper progrmammer yes there will be issues

I'd go with an S&B intake, K&N is for gassers, and a flo-pro or similar exhaust, with an H&S tuner

agreed, stay away from K&N for your LML, don't want to ruin it with dust:s:

WILL BE ADDING PROGRAMMER THATS A MUST JUST NEEDED TO KNOW IF I GET RID OF DPF AND RUN STRAIGHT EXHAUST AND AFTERMARKET FILTER SYSTEM WILL TRUCK RUN GOOD OR WILL I HAVE PROBLEMS DONT WANT CHECK ENGINE LIGHTS POPPING UP BUT HATE ALL THIS TREE HUGGER STUFF THATS ON THIS TRUCK

NO NEED TO YELL HOMIE!!!!!!!!!! and no you shouldn't have any problems, and I think the only DPF delete friendly tuning for the LML is H&S mini maxx and black maxx tuners

Why do need a tuner :humm: I was looking into this also..

Parleys Diesel Performance: H&S Performance Mini Maxx Tuner & Unlock Code for 2011-2012 Chevy/GMC 6.6L Duramax LML & LGH

I dont think he was yelling dude i think he just hit the caps button and realised it after he looked up and thought shit i dont want to re write that again..:w2:

I did the H&S programmer n exhaust MBRS. Worth it .
