so I bought and installed a DP tuner..... stock,high idle, 60 DD, 80 tow and 60 tow.
Mostly use 60DD and 80 tow around town. It came with no directions or safety messages, so
My questions are????
1. Cold starts, should I put it back to stock or can I leave a power setting on?
2. The power band seems consistent with stock, but for 60DD, is the best mileage rpm band still below 2000rpm?
3.any thing else i should know about using this thing safely? (please dont start a DP, PHP, TW debate)
New or used? Just so you are aware I am only posting the following to explain your posts about not receiving instructions. If you purchased it thru a dealer you are still welcome to pull our instructions off our site.
When a new order is placed and a valid email address is given you are automatically emailed ALL of our installation instructions to keep on your computer. We receive a confirmation email that an email was received on your end. If it was purchased used instructions are located on our website under knowledge base. If you did not get them thru email due to spam filters on your computer we put the following instructions at the bottom of your invoice in the box with your chip.(read below) Check your invoice for this statement.
The Installation instructions were automatically emailed to you when the order was completed. If you did not receive them make sure you view them on our WEB site before proceeding. Knowledge Base
Changing levels while the vehicle is UNDER LOAD is highly discouraged. While it is extremely unlikely, due to certain processor limitations there is a very slight possibility that the vehicle may run erratically or stall when changing positions while running under load. DP-Tuner recommends that you DO NOT change positions during any driving conditions in which loss of power and/or control could put yourself or other drivers into a dangerous situation. This includes, but is not limited to, driving in heavy traffic, over steep grades, around curves or through intersections.
DP-Tuner highly recommends that you operate the vehicle at moderate speeds until the vehicle reaches normal operating temperature. Failure to do so may cause serious damage to the engine and/or transmission.
It is highly recommended on "High-Idle" calibrations to start the vehicle in a normal idle program, allow the idle and oil pressure to stabilize and then switch to the "High-Idle" program. Failure to follow this procedure may cause premature engine wear and/or engine damage resulting from excessive RPM and lack of adequate lubrication during initial start up."
In the event you cannot view these we answer emails on weekends and I am on our facebook page throughout the day.
To answer your other questions:
You should notice no real power until your truck is up to operating temps. This is for the safety of your engine. Do not go WOT until your truck is up to operating temps. Best advice I can give you. As for safety with the tuning, you can't make too
much power with stock injectors. Keeping the rmps' around 2k is the sweet spot on our trucks to achieving the best fuel mileage.
You can start in any tune, just don't flog the truck until its up to operating temps.
You may ask why we don't print out instructions anymore....
We had a pretty good increase in our hardware cost. Instead of passing that on to our customers we made other changes. We tell everyone this and those who don't have email or a computer we send instructions.
I hope this answered all your questions.
