Hi Rob,
no worries,I am here to answer questions!
You can do the reflash easy yourself,even easier,if you are hand with the computer.
The Alpha-N upgrade does not involve buying any other parts.
Two things have to be phsically done to the car:
The first thing is connecting a laptop with the cable(which is sent to the individual customer via mail) to the OBD port to download and upload the software.
The second thing is to disconnect both MAFs,pin out and isolate 3 wired of the bank2 MAF connector and reconnect it(reason is,the intake air tem sensor is located in the bank2 MAF and is still needed as a value).
We will guide every customer through the process of downloading/uploading the software.
Usually we log remotely into the customer computer and install the driver for the cable.
Nobody out there is left alone on his/her own doing the upgrade.
There are plenty of threads regarding our Alpha-N

Basically,the throttle response in normal and sport mode is way smoother and linear.The jerkyness in sport mode gone.The car drives like a car with throttle cable,throttle input is linear to throttle opening.
And never ever the need to buy MAFs again
Nice feature is the sport button memory funtion,btw...
I hope you understand,that I will not comment on the advantages our software has compared to our competitors.
But I can say,that many of our customers had already software from well known companies on their cars before we did them.
And they were surprised that their car performed even better than before.
Cheers,
