GM is usually at either the knock limit or MBT. It's not 1992 anymore, they know how much timing is ideal at each condition. If adding the supercharger is transparent in that region, there is no reason to reinvent the wheel with spark timing.
Um, thank you? That was actually the goal. We didn't want to make the vehicle difficult to drive in traffic or parallel park when all you have to do to get full power is move your foot a fraction of an inch. You have the option to modify the driver request table if you want to make it more rowdy. Be aware that you will trade "sportiness" for street manners and potentially safety. The delivered calibration struck what Whipple believed to be a good balance, similar to what I have done on several other DBW programs.
If the throttle is opening 100% at 100% pedal input, that's all she's got. Final vehicle results can vary drastically depending on axle ratio, wheel/tire size, or vehicle weight. I had a program a while ago where we had a supercharged GenV truck that drove awesome and then they put a set of BroDozer wheels and tires on it. It lost 80rwhp on the dyno and didn't really feel supercharged anymore from the driver's seat. That's just how much impact the rest of the vehicle can have, even though the engine is making boost/power. That said, holding a transmission gear 10-20% higher at part throttle makes a world of difference on what the driver feels too.
