how come the throttle only opens to 87.3%...feel like I'm being jerked on the 13%, i know from tuning 90s turbo cars one of the first things they do is make sure the throttle opens all the way. my KIA optima opened to about the same exact value. on my 2016 yamaha r1 the throttle was set to around 88% and one of the things the ecu flash does is open the yamahas throttle to 100%.

Just to add to this, the Throttle body is actually oversized per a few tuners. So no need to open 100%.

From what I've read Lap 3 was able to perform flash tunes on the Optima. Nothing like that yet for the Stinger so even with more air they're not able to adjust the fuel trimmings.
