You have to consider there is one person doing this job. the gas tank needs to be cut open and have another pump installed, resealed, recertified. Gas system to be installed, high flow cat to be installed, then tuned. I have no idea how long it is supposed to take really, I am only going on what I have been told by my tuner, and have every confidence in Pitlane. As Kv said, I would prefer it to take longer and be right rather than rushed and have problems.
