You also pay for the R&D as well, in depth R&D costs lots more than developing a new map from scratch in a day and calling it complete. Believe me some companies do much more than others.
IMO I think the likes of REVO and APR justify their prices with that I mind, also considering the volume of maps in differing climates, altitudes and development of the higher stages of tune that they have running on any many cars or running the software on racing cars etc means there is also the factor of their maps being proven much more.
On topic though, I'd happily run either pump. Both run enough fuel pressure to support the extremes of the TFSi mapping.
I know exactly how much R&D they all do, including Shark. I spent a long time speaking to them about how they do things before deciding to go ahead and become a dealer. If I didn't have 100% complete faith in their maps and the way they develop them I would have gone elsewhere and we did have that option. Anyway, enough said on software, I'm not getting into map debates on here as we will never win
One thing we will never do is sit here and say that REVO/APR maps are crap because they aren't, I just think they are overpriced.
As for the pump, we have to appreciate that Simon and his team at LOBA don't want to give away the spec of the pumps. Like I have said they are running on a lot of cars now but I probably shouldn't say too much until I have put one on my GTI, which will be soon. Just to say that as with the above comments, if we didn't have 100% faith in them knowing what they are doing we wouldn't sell it.
