Does anyone have any alternative turbo speed measurement sensors in use other than Garrett? The sensor for the efr's doesn't look hard to adapt. I really would like to add this as a parameter but the Garrett kit is 500+ and I'm not interested in a gauge. Just a logging and tuning device

 

It looks like full race sells a BW sensor kit for ~150

and these guys sell the garret kit - gauge for $350.
