you have to go with the GReddy Profec-B boost controller. you can get that and the wireless remote for $435 at www.suprastore.com the remote switches the bc from low boost to HIGH BOOST. its sweet, plus, thats the boost controller that they used in Craig Leiberman's 700hp supra. What turbo were you thinking about getting? because if you said you were going to have 800 hp you arent fooling around are you? let me know what you had in plan and i might be able to help you choose some stuff. i know what works best (mostly) but its pretty much all opinions.
