This depends on many things and may require further discussion with Jody or James. Some of the factors involved in answering this question are:
Do you have gauges? Monitoring EGTs is very critical and one of the most important parameters of a diesel engine especially when you are adding a chip and increasing fuel as this can increase heat.
Do you have an aftermarket larger diameter exhaust? This is important in helping get that hot exhaust out quicker and keeping EGTs manageable.
All of the programs have detailed info beside them but most people have a basic need of programs. This is a tow tune, or even two tow tunes for dedicated towing. An economy program for daily driving, non towing and a performance program for maximum performance. Choose the tow program that best represents your towing weights. I would not suggest the 140 programs for maximum performance if you have a stock high pressure oil pump as you wil not see full benefit and may actually perform worse than a 100 hp or 120 hp program due to the demands on the high pressure oil pump.
If you have specific questions on tuning for your setup, please email James at tech@dp-tuner.com.
Please give all info on your truck. Towing weights you will be pulling, mods done to the truck, including if you have aftermarket gauges or not, and also how you use your truck and what you are after. James will put together a recommendation for you. If you need to talk to him over the phone please include phone number.
