What's "break boost" mean?

Very fun night last night... fun meeting all of you ppl. Scary trying to race ppl with my brakes grinding very badly. If the IS300 guy posts on here, we need to race again but make it fair... =]

SilviaK93 - Come to TunerFest... tee-hee. ^.^ - I'll race ya from xx - 120mph from a roll if ya want. And yah, I am scurred after 120mph... you try holding as much boost as I am on a small turbo like mine... it's very scurry. =]

Next time, lets organize a better meet with a camcorder and I'll make some vids of everyone... even if I do lose, I'll still make the vid.
