They are the same in that they both up the timing to get more RPM out of the motor..

Except that Turbo will only kick in after a measure of time on full throttle.. meant to give an extra kick of speed on long straights. I think a common delay is like a half second of buried throttle.

Turbo is a very bad idea on a hot motor... with it a full pull on the trigger can cause you to break traction and fishtail when you are planning to go straight and fast. I use it on my 17.5 buggy, but not my 8.5.
