What about Simple Digital Systems?
We completed the install of a SDS sytem for a customer who started, but couldnt finish the install. SDS is just what its name implies..simple..It is a very good system and easy to tune. No bells and whistles, no boost control curves, no fan or water spray circuits.. it has just what is needed to run the engine.
We have even been in contact with SDS about becoming distibutors.
