I recently upgraded my Corvette by swapping out the stock LS1 with a new Texas-Speed 408. In tuning my VE table I started out seeing numbers from my log file histogram around 30, 40, 50% for my STFTs (LTFTs I turned off). As I work the tune the histogram is getting numbers closer to 0, right now after 3 or 4 iterations they are 0 +/-10% but many of the values are 110 or so in my VE table. My assumption is that is because I simply have a lot more volume in each cylinder than the PCM and thus VE table is expecting, but I did change the General parameters to say its a 408 ci "6.0L". Is this normal / okay or am I needing to change something else? The afr is staying about where is should be for the most part, even when I have added 30% across the entire VE table the wideband seems to read about the same before and after.
