We have a constant check engine light for out 2012 D/A for exhaust sensors and the DEF system. The DEF tank, heater and pump have been replaced 2 times under warranty in 2013 and 2014. We had 2 exhaust sensors replaced under the emissions warranty in 2014 and 2015. In September 2017 I had to spend $680 on an exhaust sensor that Chevy replaced in 2015 but would not cover again. Now the check engine light has been on again for over 3000 miles, showing codes for 2 more sensors with Chevy estimating a cost over $1200.

So how about the delete party everyone talks about? Sinister Diesel wants $2600 for EGR and DEF delete that includes a new stainless exhaust, 5 step tuner and a display screen.

A local company where I live offers an $1100 package that includes new stainless exhaust with just a "flash" program to delete the EGR and DEF with no tuner or display. Truck runs stock.

I guess I dont fully understand the difference.

I work on and modify these trucks over in the Utica area. I would be happy to quote you on the job and explain the differences of what you're getting. I am unaware of any reputable shops in the syracuse area doing this sort of work. Its also worth noting you should avoid Sinister like the plague.

Your truck is not required to pass any emissions testing, it simply gets a safety inspection. In NYS we have what is known as the a DEMA, or Diesel Emissions Metropolitan area which is a 6 or 7 county area around NYC where trucks must pass some form of emissions testing, which if I recall correctly is just an opacity *(smoke snap) test.

For guys wondering how all this works.... If the proper parameters are mapped out with whatever software is used to write the tuning, it can be written in such a way that it shows all readiness monitors as complete.

I delete a TON of 2011 up trucks, Ford, Chevy and Dodge alike. DEF problems are borderline inevitable, the GM dealers in this neck of the woods seems to be totally inept with Duramax, and the Dodge Dealers seem to be hit or miss. 2 out 3 Ford dealers are on point, but they have had ALOT of practice and often 2 or more Diesel specific techs on staff.
