Ran my MRT speedo for the first time last weekend
Though I only ran stock, it performed flawlessly throughout the day.
I found the turbo start feature to be very good. Whilst it didn't allow me to make up any positions at the start of the race (track has a well spaced grid), it did keep my car well clear of the guys behind me! - very handy to be able to go into the first turn without fear of being hacked
Nice size too, fitted very easy into my 415.
