    Procharged Durango with new 1000cc injectors

    I was finally starting to dial in this 5.7 Durango with a Procharger when one of the injectors started getting buggy. I sent them into FIC and they send me new 1000cc injectors. Pretty sure I had 600cc before. They sent the new injector data so I uploaded it.
    Truck runs awful. Light acceleration is fine but once you try to go any harder than that it breaks up. The wideband is indicating heavy lean. I've added to the ve tables several times now and it doesn't seem to be getting any better. I hit it once to get into PE mode and while it showed PE it was still heavy lean.
    I tried running it with ANN on but it was the same if not worse.

    Any ideas? What am I doing wrong. Rich while idling and lean while on the throttle

    Looks to me, the inj where a little big ?
    0,065ms min PW are not possible at idle and 0,5 ms are too long, so its rich.
    At higher rpm 4ms seems a little low.

    Under engine diagnostic the torque/airflow/map delta/Barometric sensor data seems not correct for SC. Look at similar tunes....

    That is the data provided by FIC. Connection. Should I just start tweaking their data until I can get it to run right?

    No Fuel Trims...maybe by missing map calculation.....engine diagnostic....

    compare a few tunes and get the informations of these missing settings to create the tune.

    No trims as OL is not ready...how many times I need to repeat that here?

    Best advice ever, just compare tunes....

    I turned all the fuel trims off to tune this properly with a wideband. I didn't catch the negative timing so nice catch on that. That explains why it's running so shitty. Still doesn't explain the fueling issues. Why is it so lean and so rich in different areas. I started with a base tune from Ripp, this was there kit. Car ran fine on it originally.

    Ripp files are not even a good base, I mean it should run but...it could be better.

    So the injector data was all bad. They labeled these 1000cc but they were 60lb injectors. I put the old data in and we're cooking again. Still getting some negative timing on heavier part throttle. ANy ideas what would be causing that

    At full throttle I got some knock which is a bummer. Timing is already under 10 degrees.
    I'm gonna try some fresh 93 octane and see if that helps. Will cat protection pull timing? I thought it just dumped extra at em. I have those fields maxed out to avoid this already.
