Stroker tune difference?
What changes does one need to make for Stroker start up tune?
Guessing the tables with bore/displacement (346 to 382), and maybe up the VE 10% (382/346=1.10ish)???
Seems MAF freq is airflow that should remain constant from previous MAF tuning...nothing to do with engine swap (I am relocating to the front of the TB vice at the CAI though).
Same injectors and intake from the 346...that should stay the same
Other considerations I am missing?

You need to remap your entire VE table Jim, it's not going to be a "global" change if you want it tuned correctly.

Thanks Doug
I can do that and understand the process, I am just looking for whats needed for first run/break in tune (new build), then it will get the full tune.
Just don't want to mess anything up on the startup/breakin

with ls1 computer all you need to change is the cylinder displacement field. with the newer GMVE based VE tables, that field gets integrated into the GMVE table, so if your displacement went up 10%, now our GMVE will be numerically 10% higher as well.
MAF is a completely arbitrary calibration, so any alteration to the intake tract will require recalibration. The only real problem with a stroker occurs if you're flowing past the limit (512g/sec) of the MAF table.
