The ME2.8 is a fairly easy ecu to tune that can be tuned fairly easy with some new OBD tuning plugs
You can also do this easily for free as long as you have some tuning files from the underworld and a 100$ ktag or kess clone.
This device allows you also to tune your transmission in 10 minutes depending on models.
The STANDARD rules are stages. If you get a stage 1 tune, the mapping is not for bigger injectors
It's easy to understand why: You add more fuel, but not more air that should be sone by a intake modification
changing hardware is part of stage 2 tunes
In your case, if the tuner send you a device with a stage 1 tune and that you swapped your injectors to bigger, the tune is no longer optimal
if they send you a stage 2 tune that has been mapped for bigger injectors , they must have told you what injectors model to swap to and hardware to change
then now you have a stage 2 tune.

Then I wanted more power .... so I went "Stage 2" ... and this includes a 76mm Supercharger Pulley (much smaller than stock), 1-step colder spark plugs, bigger flow injectors, belt wrap kit, and improved cooling (high flow pump and bigger intercooler)... and of course, I got a new ECU tune file from RaceIQ to accommodate all the new hardware improvements. I did all the work and upgrades by myself in my own garage. The results are very impressive. Car runs like a champ.
When I get bored with this... next step will be bigger throttle body and potentially a larger crank pulley, and yes, i will have to reflash the ECU again to accommodate these updates as well.

On the other forum there had been some speculation that a setting within the engine ECU could produce a small bump in performance. U.S. cars are set to use ignition maps for 91-octane fuel. But in some eastern states 93-octane fuel is available, and using DAS the engine ECU can be configured for the higher-grade fuel as follows:
.
Control Units > Motor Electronics > Adaptations > Correction Programming > Ignition
.Rodney played with this and noticed no difference; a friend of mine said his highway fuel economy improved slightly.

I think they advertise the ECU flash as adding 32 HP.

Also, for stage 1, I am pretty sure the tune itself has to do more with controlling the boost levels from the Supercharger than fuel octane levels. Most of the tweaks are done around the behavior of the SC bypass valve so more boost is preserved.

Back to the initial discussion, always better to read what people that did the updates think of it:
