I have one but I'm waiting to fully debug the car before starting to use it (so no useful feedback yet). Installation ease will depend on what harness you are using and what you are doing (or can do) for wheel speed sensors. The digital control is a must have.

I've used it in a turbo Supra, and have to say it's very impressive. You'll spend time getting it dialed in. Well worth the money if you have a setup that puts out too much power...
