Below shows what I have seen in my car (here at 4700ft).
Stock Pulley 13-14 lbs of boost
Code 3 15 lbs
181 17 lbs
Code 3 & 181 19-20 lbs
I am curious why some of you see such low boost levels with a Code 3. I see 17lbs in first and second gear and 18-19 in the top of third. I also have no belt slip to speak of. I do have one of the first generation pulleys without the continuous groves....I wonder if that makes a difference??
My 12.2 was with my car weighing exactly 100 lbs more than 240M3SRT and sowardcustoms SRT6's due to all the stereo equipment in the hatch. It may have helped to have the extra weight back there to offset some wheel spin.
