There are plenty of aftermarket company's that can delete and tune the ecm to not look for the aftertreatment readings so you don't get check eng lights. and HP update can be changed with a recalibration if the engine can handle the uprate. I always used PDI they are a bit expensive but their products are good and you send your ecm out to them they will program it as needed and return it within a day or 2. Give them a call if you wish and see what they have to offer for your concerns. http://pdidiesel.com/
