The Tekin Gen 2 is a great speedo, especially if you were going to be running just stock, but you need to think ahead and the chances that you may run a hotter motor in the future ??? If there is a chance then the Pro would be a better bet as you wouldnt want to shell out on another speedo and get frustrated, both speedo's would be ideal for your current needs, but the Pro may be a safer bet if you were thinking of a hotter motor.
