I finished tailoring my basemap and the car pulls much smoother now. I eliminated the 4k dip and trimmed up the timing... the curve is definately smooth, but the peak numbers aren't much different. Tomorrow or Monday I'm going to finish up the tune and I'll post my results. After that I'm going to install the S13 240/248 combo and see what it looks like.
From there I might build an intake pipe with an open filter to see if any intake restriction is holding me back. Since I'm tuning the AEM with the MAP sensor I can completely delete the MAF.
I'm curious about intake manifolds and wilder cams, but I'm trying to map out the average 240sx owners options for cheap power in order to help out the community.
