They will tell you the PCM cannot be flashed to accept a larger tank. They likely will not disable the DRLs also because they are required in CN but anything is possible. The float in the tank will still register the correct amount of fuel for your dash needle. The tank is longer, not wider or more tall so the same level of fuel is the same. If you have an OHD that reads DTE, it will not go above what the PCM is set for but as the tank runs down the DTE will still read correctly.
In other words, say on a 26 gal tank you can get 15mpg so you should be able to run about 390 miles to empty, right? Well with a 25 gal tank and the same 15 mpg you would be able to hit 525 but the DTE will still only max out at 390. However, when it reads 10mi to empty, thats what you got so dont push it

Our 03's have a body computer (BCM), a powertrain computer (PCM), a trans computer (TCM) and if you have an OTIS/EVIC in your overhead console, a trip computer.
