Hey guys just purchase the D1 and installing next weekend. I have the 340 pully est 15lbs boost and a 400 pulley est 10-12 lbs boost. I have the lt1 edit and turned timing way back and set it close to 20 degrees at WOT. Does this sound about right? (stock bottom end). I'm also looking for a larger pulley to help me tune with less boost. if anyone may have a 4-6 lb pulley and or belt 12 rib 40-42-42+ inch belt. just let me know what your asking price is and I will get in touch with you. (also Twin core intercooler)

Any Help would be greatly appreciated.

Ken
