Well actually, I have been hearing some not so good things about the mixture display kit lately. So dont know whether I will go ahead with that just yet. Also, dont trust the local places to install the Jaycar gear around hear, I will wait untill I come to Sydney for Autosalon to do it. So couldnt give you a valid price at all.
And yes, Mixture kit displays whether your running rich/lean using 10 led lights...
