I just recently picked up the LS3 525hp crate engine (stats in link) and I have the tune running fairly well but there's just some little quirks driving me crazy.

I was just wondering if someone has used the 99-01 PCM's with an LS3 and have their tune that they would be willing to share for comparison? I feel like I'm missing something simple that I'm just not putting my finger on.

 

Anyone?

 

You will need the 58x/4x-to-24x/1x crank/cam signal converter from LPE.

 

If I didn't have that (or swapped out those for compatible parts) I wouldn't even be able to run the car.

There's also a lot more you need than that.
