You can do all the complaining you want when you spend good money for an expensive product. Just my

It's not really a good idea, IMO, to do any R&D on your customers dime. Just imagine if our shop said, "We have this new bad ass turbo like none you have ever seen. It's going to kick all of the other turbo's asses! AND it's going to cost you $5k, but if you want to buy it first you will have to pay about MSRP to be first." Then our customers get it and it makes no power or breaks when you boost. Do you honestly think we could just say, "Oh well. It was a brand new product, screw all of you who bought it first. You should have known there would be some issues and that's your bad. It says right in the fine print that the turbo was not really meant to boost. But no worries, thanks to all of your complaints, we're going to improve it for the next round of buyers. It will actually boost this time. You, on the other hand, are fucked and we aren't going to warranty it."
I think we might be in a whole lot of trouble.

Just my take on it.
