I'm seeing 38 with only intake, exhaust, and Quadzilla Max Mileage. The QMM has a built in boost fooler which I think basically just makes the wastegate hold out longer before it dumps.

I have the edge juice with attitude along with intake and just straight pipe, i have seen 38-40 boost psi before, and i have the backdown turned on so if it hits 38 it starts backing it down and it has backed down as much at 45%...

Sorry, I may have spoken out of turn here, my truck's an 06. I think the stock 06 got a little more boost than the earlier models?

all you need to do is download the SO6 software on your smarty (Mads Electronics - Smarty - CaTCHER - Dodge Tuning - Home) and turn your wastegate off (its an option on your smarty). before i only had 32psi but with it off i get 45psi

call me nancy but... i do not know about turning the waste gate off! i cannot believe there is not a "tuneable" setting insted of an on/off. my bud suggested using a boost elbow andthem putting a manual valve on it where you could set it say for 42 or so.
