Are Pontiac GTP L32 vs L67 timing tables different?
I run a 2006 3800SC L32 engine and am using a 2003 PCM to control it.
When I compare the RPM to air mass timing tables I find that the 06 timing values (in the table that I discovered here) are far more agresssive than those in the 03 program.
This is what I have decided to try (the 05 timing numbers in the table below )over the 03.

Does anyone have any idea if these timing numbers will work on my L32 2006 GTP 3800Sc engine w 3.4" pulley and short stack intercooler? The timing numbers especially at the high air mass values are about 3* more timing than before.
