Figure this one out......99 Camaro, 00 Impala, I was comparing the VE tables....I expected that maybe there would be a bit of difference, but holy crap.....(I can't figure out how to copy the tables to here).....

Anyhow, as an example, the Camaro VE at 20Kpa MAP and 0-6400rpm is
31,34,46,50,54,55,57,59,60,60,58,56,53,50,42,36,29

The Impala VE at 20Kpa MAP and 0-6400rpm is
65,48,44,44,44,44,44,44,43,43,42,42,42,42,42,42,42

Does this actually look like it's stock, or modified?

The PE enrichment Add vs RPM is also significantly different, as are the timing tables.....

I'm assuming that this is a 3.8.......but is there an HP Tuners for 3.4s?
