I fired up the car today did some logging, my car is split in almost all Cells. I'm running 30* of timing at idle and pulling in a map of 48. I 'thought' that with that much timing at idle, the Map would be lower, but when I jumped it from 20* to 30* I saw no difference.

Does that sound like there's a vaccum leak?

It's a CC305, 58mm BBK, LT4 Intake/Heads, MTI ported, 383 9.5:1 Compression.

The link below should be pointing to a log:

And you can email me at fb_nitro@yahoo.com if you want to see a copy of the program.

 

did you try swapping o2s, then try to find leaks on the left side (when sitting in car) on the headers intake everything. then swap the injectors to the other side one might be stuck open.
