Was wondering if any of you vendors could get me a good deal on a PPE programmer. Or if anyone else knows a good spot - thanks

I also was wondering if this actually works:
2001-2004 LB7 Boost Increase Valve [FGBSTVLV0104] - $29.99 : Pacific Performance Engineering, Innovations in Diesel Performance

does it just take more pressure to actuate your wastegate?

Bumping it up for you. Also the Boost increase valve does work, it should put you up close to 30 PSI of boost if you are running enough fuel to get there.
