[QUOTE=ash 26;11745811]I bought mine in 2009 new of Wren and changed my plan and had no home for it till 2011 at that point I was aware of the issue regarding the compressor and got onto Wren about it I send the turbine back to them unrun and got them to carry out the upgrade of the compressor and the diffuser at a nominal charge as technically the turbine was now out of warranty the whole issue was dealt with in a very professional manner by Wren

Why did you have to pay even a nominal charge for an upgrade? Again, the owner has to contact wren about the issue, then the owner has to send it to wren, then the owner has to pay wren for his new but "old and out of warranty engine" to be upgraded or repaired? And people are seeing this as " very professional "? Did wren ever communicate to 160 owners about a potential problem? No, they simply waited for these engines to fail out of warranty and then proceeded to charge for repairs and sell upgrades to uninformed customers. Even my engine had ecu problems that caused flame outs with the original owner. He sent the engine back to wren and was promptly charged for a ecu upgrade to projet even though the engine was still under warranty, he paid the bill and also thought the service excellent! Why did he have to pay? Why would anyone buy a engine at the full purchase price, then pay for an upgrade, to hopefully make your new engine reliable and safe? And then pay yet again should it fail? If you buy an engine from a company like wren, would you not expect it to be an expertly engineered and thoroughly tested and supported piece of hardware?
