i run a RT dash 2 got it from shawspeed at a good price, hooked up to omex ecu it gives alot of reading from that, no need for any other lights for indicators like the stack its fully road legal on its own. need a laptop and half a brain to set it all up but its not that hard.
ive also got a stack in another car, prefer the manual rev couter in the stack but it does nothing else apart from that
