[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

[quote name='Ruthenian' date='Jun 5 2005, 03:46 PM']Your timing for N12 through N15 is 2-3 degrees greater than mine when I ran 15PSI on stock ports with non-seq turbos.



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