I went from a 1991 5 spd 305 TPI to a 383 HSR with Trickflow's (still T-5...til it blows!)
The stock BIN is the AXXD BIN but is that the best one to start tuning with? I was thinking the 350 TPI BIN would be better but obviously it only came with an auto tranny...

Any input which BIN would be best?

 

I'd stick with a stick BIN to start out. Can use AXCN which is a 350 6-spd cal.

Yep, either AXCN or AXXD (or the more recent AXYC, which is what I started with). I'd stay away from the auto tranny BINs if it were me.

Or wait until S_AUJP V4 is released - it has the manual stuff built into it (shift light, etc.) as well as the auto, just select auto or manual to toggle between them. I've been running it for several weeks while Scott and JP fine tune the code and add features (some really neat ones, too!). I just transfer over my calibration settings (idle, VE, spark, accel, etc.) to the new version and it works great so far.
