Tuning Advice

I acquired a 2011 D with 83,000 miles in April. Background of the car was unknown but my intention was to address the issues that impact the reliability of the D's and improve performance. I've completed the CBU cleaning, ABC deletes, installed a Unobtainium downpipe, step intercooler, Provent 200 and 2 micron water separator, numerous suspension improvements and brake issues resolved.

I"m now nearing the time for tuning the ECU for the deletes and enhanced performance. The goals of the tune is first reliability of the car and enhanced performance. I live in a diesel acceptable state. My definition of reliability is minimal if any SES codes and hopefully no equipment failures for long periods of time. My annual millage will be 25,000+.

I'm looking for advice for who and what level of tuning for my goals. I love performance but at a point in my life (it's taken me 5 months to get to this point on the car) I have minimal energy to deal with a pain in the AXX car.

Thanks in advance for all of the feedback.

40,000 miles on a JR stage 2 tune here. I average 20,000 or so miles a year.

I have JR too and it works fine. As you know, when you removed your DPF the clock started ticking to yank or gut the SCR, maybe 5,000 miles. Or maybe you did that, I couldn't tell. You must have a suntan from the CEL being on all the time.

JR 2 for 15K and now 2.8 for another 15K, zero issues. 2.8 coupled with ATM intake leaves minimal soot on back bumper.
