I am curious to see how these perform then they come out vs the GC's
I think reliability is of more concern. The GC's had their issues but it appears VTT has fixed the deficiencies. I don't know if MMP has addressed theirs. But I haven't heard of MMP pulling a Helix and shafting a customer, so even if you experience issues MMP does warranty their product.
Well I mean the real problem is the parts (vtt, mmp, pure). They are all using a similar turbine wheel that has issues. At some point they have to choose going out of business or taking care of the customers but if they go out of business then no one is getting a warranty. I have the new VTT turbine wheels and look forward to seeing what type of beating they can take.
