Default 04 z06 procharged tune.

its an 04 zo6 ls6 with a p1 on it i bought the car with the procharger on it.
and when i go wot it cuts out and sputters really bad. it acts like it runs out of fuel. but seems to clear up after about 5300 untill i change gears.
and sometimes not everytime it wont go above 4k without cutting out real bad.
i have hp tuners and im trying to learn how to tune it.
i thank you for any help.
im still trying to learn hp.
i data logged it and at 6662 the timing is at 13.0 and the injector duty cycle is 126% maf is at 58.54 map is 15.0 is it running out of injector?

It's def running out of injector. The MAP reading can't be right, or you are reading it wrong or something.

I would check the plug gap first. Could be why it's breaking up. Should be around .030 or so. Check that, and get some injectors in it, and if you're wanting to tune it yourself, get a wideband.

What Ed said, plus - does it have a fuel pump booster? If so, is it hooked up and working (fuel pressure rising when you go into boost)? If the car supposedly ran good before with this setup, that could be a cause for it running bad and the extremely high duty cycle...

There's several different ways. Why don't you post the tune so we can see what you're working with?
