Here is what's happening so far. My little 4.8 with a LJMS cam and KB racing s369 kit, 20" wheels, 3k stall. This is at 12 psi, 5* timing and 11.4 afr. We are going to drop to the 9# spring and add some timing

 

Why so little timing?

 

Weird that it is only 5° timing .

 

We are keeping the power down for now as to hopefully extend the life of the tranny. Also, I have pizza slicer tires (255/45/20), so anymore power will be useless. We think going to the 9# spring and adding timing is the way to go temporarily.

 

LOL!

 

Ya then lower boost and add timing because that little timing is not good.

 

Ok so here are some more results from today. 11.4 afr, 7psi, 12.5* of timing:

 

I would be interested to either see a 3rd gear dyno or a video of the boost gauge on the street, seems kinda laggy tho

 

He's still getting it all dialed in. I'll see what I can do when it's all said and done.

 

Here's a vid of a dyno pull on 7psi, 14* of timing. Put down 450rwhp and 440 rwtq
