I'm not sure who started this thread about the twin turboed Camaro,
but I want a ride in it!
I'm not sure how you specify it w/DFIs, but the timing & fuel tables
in a stock Syclone (2 BAR) "might" look exactly this:
Deg. vs MAP & RPM

Remember this is a 4.3 V6 that pulls like a jet till 4,000 RPM.
Then goes to sleep. They have low perf ports & cam, and a
small turbo. HTH
