It's a Sprintex SPS/210+ kit with 69mm pulley. Positive the peak was 12-13psi on the dyno.

Did some logs yesterday/today with some spirited driving.

MAP is in kPa absolute.

137kPa absolute = 100kPa atmospheric + 37kPa (5.3 psi) boost.

Is your MAP sensor scaling right? Which sensor are you using and which ROM address did you adjust (the original def sensor scaling addresses were wrong). Just had a look at your logs - your MAP is pegged high at 137kPa which looks like a maxed out stock sensor. The psi boost value is in your logs as manifold_relative_pressure.

Stock sensor scaling = 250mmHg/V -150mmHg
Stock sensor at 5V = 1100mmHg ~= 145kPa

ps: you can delete the AF_Corr_3 and AF_Learn_3 values from your logcfg.txt - I'm sure the latter is an OL_enrichment value and I haven't traced the AF_Corr_3. You can also boost the sampling rate by dropping some of the parameters that you aren't really looking at and decreasing the calcsampinterval value - I am using 500 at the moment and log 32 parameters at 40ms interval.
