    I'm trying not to confuse myself with what you typed on the compare file/write dealio stuff.

    So the computer you have started life as a 5.7 Express VAN file or it is something else?

    Adding power is good but there is still no way to gain back the mechanical advantage that is lost from the huge tires and lift kit.

    Even if you added say 20-30hp or did a 6.0 swap to gain even...

    Something wigs out if you put a tire size over like 35in in the wizard. Likely why you are getting the ABS lights if you stuck in the number 37in.

    Try creeping up on the number like try 34 or 35...

    That all depends.

    It's worth a possible 5-10hp and 13ft lbs bump on a stock engine, even GM claims that when they rated some of the GEN 4 LS V8 engines. Then if you tune it even more with E85,...

    From the log it looks like you don't have a pending or current knock sensor code so that is good. If there was it would peg out at 8-10 degrees of knock and just stay there under the right...

    First lesson here. Power enrichment is a set and forget table, if you didn't know that already. The idea is to pick a value you wish to run under boost. Say you want to run 11.0 AFR, that is the...

    Does it atleast have better than factory gear?

    If not it's lugging the hell out of the engine if you have stock 3.42 or 3.73's. Needs 4.56's or 4.88's at a minimum.

    The data log is missing a...

    Otherwise post your file.

    A wideband is needed so the MAF/VE can be fixed using that. With that you'd create a wideband error against the commanded fueling to show where fuel can be removed or added.

    The slower shift times and timing being pulled is completely normal for a stock calibration.

    Just look at the shift timing tables and you'll see how slow they are set. Shift timing > torque adder...

    The computer itself was never designed for a wideband so it could never use it in that way.

    We can only use the AC pressure circuit or the EGR circuit to log the wideband in the logs so we can...

    A few things kinda bug me. Whoever tuned it, did it as a 5.3 engine size, that does matter if you want to get technical because if you changed it to a 6.0 cylinder size, you'd have to go back over...

    Why is your flow rate set to 40lb/hr when you say you have 80lb/hr injectors? I don't have the deka data but that one setting is for sure wrong. You'll likely have to cut the minimum fuel milligrams...

    Post a log.

    Nothing is that tune should really stop it from running. It should stay running even though you may need to pedal it.

    Without a wideband reading or log to look at I can't see if...

    I don't remember needing to email support at all. Just re-made my account, added my MPVI to my devices page to re-sync it all and it was all there. But again this was over a year ago.
