    Are 62 lb injectors what you told him you have when you filled out the tune paperwork? The 02 sensors will lean out the the fuel at idle but once you go into PE mode it's gonna go open loop and no feedback so accurate data needs to be there for tuning the injectors.

    Yea Allen knew the injectors but the thing seems to be is that at idle it is fine but it will according to my wide band go rich (peg to 10) with just the slightest bit of accelleration not full throttle not even getting into boost (unless it is maybe a pound) if my gage is not exact. I am sure it is not even going into open loop unless there is another function that makes it. The tuning is all new to me I know eventually I will need to get the software so I can learn and tweak on it.

    Is it acting rich? Or is it just the wideband saying it? Have you calibrated the wideband lately

    I have not driven this much or even very hard. Part of that is that as my truck project has evolved I am upgrading the brakes and did not have them completly bleed to my satisfaction but was ansious to drive it. The other reason is my wide band is an AEM and indicates it does not need calibration plus it has always worked to the best of my knowledge with both NA and nitrous application just prior to the install and reads in that 14.5 to 15 range at idle.
    I still have to finish my exhaust from the muffler out so still have a couple things to finish. Since I was dumped right under the cab next to the passenger door the exhaust was terrible in the truck maybe in part to running rich but again I am not wanting to damage what I have just looking for information to make sure it is right. I can pull teh plugs and look and have not done that yet.

    Can you link me to the wideband you have? Mine is an Innovate and does need calibration on a regular basis.

    I bought mine locally and in part was that this gage is what the speed shop had. Others may chime in on its quality or reliability but without anything else to compare to I like it.
    I guess I better make sure this is the model they may only have one I am not sure but I know mine looks like that.
