    please help with my tune:/

    miketurbo5.3stock is attatched. this is my tune taht was tuned by a shop in springfield and the truck doesnt feel right. i would appreciate someone looking over tthe tune for me and see if they see something going on. my wide band shows some lean spikes and seems overly rich sometimes. i also attatched miketurbo5.3 which is the log for this file. it has 60lb injectors in it but the file it shows 70lbs which im guessing he was using that to lean it out some. thanks for your help guys, this truck has a 3200 converter, intercooler and im running aboutt 9lbs of boost off the turbo. cam is an isky 212/212 .561/.561 lift overlap 36deg. adv 260/260 112 lobe center cam advance 2degrees.
    injector static flow 4.0 bar 732cc at 58psi

    What config are you using? Is your wideband connected to the interface?

    I'm not sure I understand what you are asking when I say config, but it has a front mount ontercooler, about 9psi. It is mounted up by the passenger side valve cover.

    You just have to change the file extension to .hpt to get it to work.

    Which 60lb injectors do you have?

    Your Dynamic Airflow High RPM Disable is set too high.

    Your PE enable TPS is too high. I use a histogram that plots TPS over the VE table in order to figure out what it takes to get into the higher load areas.

    I'd also fatten up your Open Loop EQ Ratio tables.

    Ok should I set the high rpm disable to 3000rpms?
    What about power enrich enable torque? Should that be set at 0?
    What afr should I be shooting for at wide open?

    I'll post the specs on the injectors this afternoon

    Shoot for .78 Lambda, or an EQ Ratio of 1.2765.

    ok, just so there isnt any confusion there. do i just enter that value in the eq ratio table. and should i do that at certain rpms. such as 3000 to 6400?

    I would enter 1.00 in the 0 rpm cell and 1.2765 in 3200-7200. Then interpolate between 0 and 3200.

    Work on getting your wideband hooked up to the interface so you can tune your truck properly.

    You can hook up Wideband through the EGR or AC Ckts.

    Hooking up Wideband is a must for Wot tuning.
