    Finally got the supercharger fixed and now its running lean. Scanner says right and left banks are lean. Iv'e had Allen back the timing down already and its still pinging. Now I'm wondering if the injectors are maxed out. and making it run lean, which in turn is where the pinging is coming from. I have another month till the 6.0L is done and then the swap. But I need it to tow with next weekend. I'm waiting for Allen to return my call now to see if he can do something for me now. I got a set of 43lb'ers at home. Guess I might have to go ahead and throw them in to fix the problem.
    Anybody have thoughts on this.

    Sounds like the culprit. Stocker are only good for about 5 psi boost.

    Yeah, you are undoubtly running them at 100% duty cycle with the huffer. Bigger injectors almost always come standard with a huffer setup.

    As soon as Allen calls me back, I will tell him to add the 43 lb'ers to the tune and go ahead and do the swap. I was just going to put them in the 6.0 when I swapped the engines next month.
