This was my old 4th gear airboy. Note I swapped out a lot of parts and did weight reduction so I didn't know exact weight so I estimated what I thought was high and low weight for the car which is the two lines. Actual power would be somewhere in between.
Edit: In looking back at the log I made that picture from that wasn't even the finished tune. It is about 3.5-4* of timing off.
What took out the motor and could you give a guestimate on the torque increase from 2.0l to 2.1 soley based upon a bare bones 205 (stock with good compression)......increase of 40lb/feet?
