ummm... he was taking samples at 5%, 10%, 20%, 40%, 60%,80% and 100% throttle..hence at least the 5 color lines.. (see key at bottom) for Hp and torque for each of the throttle openings of 20%,40%,60%,80%,100% . each one of these the computer kept the throttle at the percentage (+/- 1% up till rev limiter) now unless im misunderstanding something...
oh wait...yes the 158 of course is the 100% pull... i was talking about leveling out all the fuel air ratios at all throttle settings and rpm ranges. that was his first step in custom mapping...then he worked on small modifications to specific PC3 numbers at specific throttle and rpm ranges to smooth out the curves
