Well i got this controler in today, and i must say, i LOVE it! high low is a real nice thing to have, when i cruse i run at low boost (stock) and when i wanna race, push the button, and i got 13 psi Instantly! i got it for real cheap, only 110 dollars. man, this thing is fun! I highly suggest getting an electronic boost controler, if you can. rock solid boost, hits 13 psi, and STAYS! its Great!
