I'm in the process of putting the motor back in my 92 Jetta and thinking about a boost controller. I plan to mount it under the hood. (I'll constantly be screwing with it otherwise). I've seen a bunch on Ebay for under $10. Summit Racing, on the other hand, has a 0-25 psi controller that cost over $70. I've also read on this board some people are using cheap air regulators from Home Depot. I don't want to overpay, but I don't want something that doesn't last either. What do you guys recommend? Thanks.
