Yes, what kind of turbo timer do you have? I just went through the install on a turbo timer.

 

I have an Apexi turbo timer. It wasn't too difficult if you have a basic understanding of cars, and electronic wiring. It took me all in all about 3 hours, with no wiring diagrams, and just piddling around, in reality, it could be done in about 1-2 hours if you know all the right wiring and have all the right tools. I do not know a lot about the blitz turbo timer, but I am sure the basic fundamentals are the same. The main difference, is that it wires into your tachometer readings instead of where mine wires into the O2 sensor readings to determine how long countdown should be. Let me know what you have determined on getting.
