Yes, you can add a chip to your ISL. I had a 400 ISL in my 2005 Diplomat. I added the Digi Cr chip that Parleys diesel used to sell. A couple of other RVers on another forum added the same chip. One RVer, had his dyno'd. It added 52 HP. It turned my Diplomat into a rocket. The chip did not affect the ECM. The chip was connected directly to the fuel rail. It changed the timing and fuel delivery. The good thing about the Digi Cr, it reverted back to stock settings under wide open throttle (WOT) so that you didn't exceed your Allison ratings.
When I sold my Diplomat, I removed the chip since the new owner (trade in) wouldn't know it was there or what to do with it. I figured my new 2014 with DEF couldn't use the chip, so I sold it to a friend with a 2006 ISL. By chance, I looked up the chip later on and found that it could be used from 05-present.
I acquired another one from someone selling their coach and intended to install it on my 2014, but they moved the plug to an inaccessible spot on the 2014, that I didn't want to try and unplug. Last week I was checking for other chips and found that Brazels is selling a similar chip called TS Performance. It attaches to the fuel rail like the Digi CR and affects fuel timing. The TS attaches at three different wires on the fuel rail.
Typically, Brazels has a booth at Quartzsite, so I'm going to get more info on their chip. I want to make sure it does the same thing as the Digi CR and reverts back to stock at WOT.
TS Performance
I ran the Digi CR for over three years and 27K miles. It also improved my mileage by .5 mpg.
