Hey guys. You do need a wrench to turn the lock nut. I had toy/keychain adjustable wrench laying around so i droppped it in the glove box. Works perfect.
On another note. Gave the HBC another turn in today. It didn't seem to raise the boost any. Still jumped to 13-14 then dropped back to 8-10. Although today i rolled to about 10mph then nailed it. It bogged for a second then BAM took off like a rocket. I think it can go a few more turns but i'm gonna drive around a day for each setting to make sure BLUE likes it. Plus, as one of our pioneers of this mod said, "BABY STEPS" is the way to go. I'm keeping a close eye on this BOV setup peeps are working on here and over on the SRT board. I tell ya, you CAN NOT BEAT THIS mod for $50 & 15 mins of your time! Just my .02
