I would keep the zilla if it is a reasonably maintained machine. You will never get the BRUTE TORQUE from a Banshee at mid range that your Zilla. One the other hand, if you wanna go nuts on power..........the Bnshee is AWESOME. I have owned sevaral Zilla's and think they are simply awesome......when tuned correct and maintained. Later!

 

Maybe the question should be......should I sell the Viper for the Vette?
