Turbo Timers and Boost Controllers

[zuni]

ok im looking into getting a few new products for my 89 7mgte turbo supra.

the first one is a greddy turbo timer. my first question is, has anyone used a turbo timer? How hard are they to install yourself. And i dont really understand why i should buy this other then it will save the life of my turbo. is there any other benifits to having one of these. And has anyone ever bought from suprastore.com, any bad experiences.
