The Techlusion unit is not actually made by Wunderlich (what is I wonder).
It's made by a company called DoBeck Performance in Montana. 'George' of DoBeck told me over the phone that the 1200 unit was very different to anything that's gone before or that they've done before and that the unit would be available 'in quantity' at the end of October.
FN from Advrider has one on his bike already as his bike seems to have been used as a test bed. He reports no problems and 95 bhp on the dyno using a full Remus system.
As for Warranty issues, supposedly BMW are aware that the Remus system, which they at least tacitly endorse causes lean running which could result in warranty issues anyway. Word has it that Remus are developing something to correct the problem. I wonder if Remus's answer isn't the Techlusion unit anyway?
