[B] I don't know if I am too lean, too far advanved or don't have enough amplified ignition (stock ignition at the time).

I was trying to run only mechanically limited 10 psi. My wastegate spring jamed and it went to 16.6psi and spit the apex seal. The LM-1 showed lean but it would with a misfire also. Do I seem lean to you guys?



I'm running 550's and 1680's my recaled base map is:

row P 18 from N12 over toN20 -20.4,21.1,20.9,20.0,21.0,20.0,19.1,18.0,17.2

row P 19 from N12 over toN20 -23.8,24.6,24.9,24.9,23.9,22.9,21.8,20.5,19.6



For PFC Leading Map I'm running

row P 18 from N10 over toN20 -10,11,12,13,13,14,14,15,15,16,16

row P 19 from N10 over toN20 -8,10,11,12,12,13,13,14,14,15,15



Thanks, Barry

if you broke an apex seal it went lean or too much timing advance

timing looks ok. it was prolly too lean

Do not know what type of porting you have, but I say you have too much timing.

lean depends on too many things to just look at the duty #
