2001 Duramax... some questions.

Ok. I have purchased the diablo predator from summit racing, along with a straight thru 5 inch exhaust and a k&n cold air intake. Needless to say, i am THRILLED. This truck was a dog compared to what it is now crazy how something so little can make such a difference. But, ive been running in stage 2 and 3... put it in stage 4 once but idk i was scared it was going to hurt something. Whew! son of a gun HAULED! But we got on it right away and it was before the exhaust and it didnt sound right... someone mentioned to me about tranny relearn? can someone explain that to me? so basically...

Is stage 4 safe?

If it isnt, what can i do to make it safe?

Also, since i ordered this from summit... are there any updates for this device? I really appreciate any answers that you can give me. Thanks guys.

You want to drive around lightly for the first 50-100 miles to let the trans relearn, other than that, enjoy

The extreme tune is just that, but can yield great mileage if you dont drive like a lunatic

Thanks
