I posted this over on Diesel Bombers and since you already have a "chip" (the Ottomind), then putting a programmer on it will do nothing.
Here's the deal, plain and simple:
A flash programmer reprograms the flash memory in the power train control module (PCM).
It alters the way the PCM calculates outputs based on sensor inputs.
A fuel module (or HPOP module in this case) like an Edge Juice (or "10K"-style mod) alters inputs to the PCM therefore affecting the output of the PCM by fooling the PCM into "thinking" the injection pressure is lower than desired so it increases the injection pressure.
A chip bypasses the internal flash memory of the PCM completely ignoring the programming in the PCM that controls outputs. The outputs are controlled by the programming on the chip.
So, based on the above information, we can see that "stacking" is possible with two combinations we have seen. You can "stack" a fueling module with either a chip or a programmer, but you cannot "stack" a programmer and a chip and see any difference from what the chip is programmed to do.
What will "stacking" do for you?
Usually, it results in a check engine light and a code P1211 because the high pressure oil pump cannot keep up with the perceived demand. The tuning on most chips and programmers usually alters the desired injection control pressure by commanding an increase in injection pressure under most operating conditions. This helps a good bit with efficiency and power. By installing a fueling box ("10K" mod-style device that fools the PCM into creating more injection control pressure) in conjunction with aftermarket tuning that already increases the injection control pressure, you can see that the high pressure oil system will be taxed to the max. Not to mention that most studies have confirmed that 3200 PSI is close to the limit of efficient operation for stock injectors.....a lot of programmers and chips command near that amount by themselves. Add in a false input to the PCM that will cause it to try for more pressure and you can see where you'll run into problems.
You can run a chip on your truck or you can add in a "10K" mod device. It's up to you. However, you will simply be wasting your money. Oh, and if you do get a chip, DO NOT try to reprogram your PCM with the chip installed. You can keep your PCM reprogrammed with a chip installed, you just won't use the programming from the programmer while the chip is installed as whatever "tune" is loaded will be bypassed. If you run an injection pressure fooling device, the ICP data will be lower than actual and the IPR duty cycle will show up higher than normal on a scanner.
You can take this advice as it is and ignore it if you'd like to waste some money or you can put that money to better use somewhere else.
