Unlike the older EGR engines, We are not seeing as big a jump in ecconomy as your friend is seeing.
At 2-3 mpg improvement, you will save around $25 in fuel every 1000 miles of driving at $4.00 per gallon. The DPF Delete and tuner cost, What? $1200-$1500 so it will take you about 60,000 hiway miles driven to save enough in fuel cost to pay for the conversion. Around town and towing mileage improvements won't be as high and will take longer to achieve pay off. There is also some cost savings for DEF that I haven't considered. So add another $4 every 1000 miles or $29 per 1,000 miles.
Rich, I know for you, that you drive that much in year, So you are talking a 1 year payback. But most of us won't see enough mileage improvement to justify the cost for several years.
So the man reason for doing this for most folks is the percieved performance improvement. The plain DPF delete is only 30 hp increase. For me thats not enough reason. If you step up to the higher tunes, yes there is more horsepower, but then you've really traded off the mileage improvement for the extra hp.
For me, I'd have to return it to factory every year for my annual emmission testing. So it's a big no for me. If your DPF is plugged and needing to be replaced and you live in a non-emission state, Then I'd replace the DPF with a delete.
I'm with you this. Not to mention, I'm no where near my warranty end. So she is stock for now.
