With all the the VE tuning debates within the 3800 community, I decided to try an experiment to prove/disprove the debate.
For my 03 SSEi, peforming a VE Tune (4 tunes to get LTFTs within -3%/+3%) did not make ANY difference in my subsequent MAF tuning.
Attached is my before and after VE and MAF tables. The before VE table was the stock table. The after VE table has significant changes above 2400 RPMs.
The MAF tables ended up VERY close regardless of which VE table was used.

So far, chalk up one for VE tune does not matter.
