When ever I am going any where in the bird, all I have to do is romp on the gas and I get a chirp. 75 romp chirp. I am so looking forward to try the 1/8 mile strip we have down here. It hilarious when I am at a stop light and person next to me takes off hard spinning tires, I just nail it and chirp. There eyes bug out. Its great to have the chirp!
