Hello guys,
I've been trying to tune this mustang, it's my first s550 turbocharged. I've been reading a lot of posts inside the forum, they have been a big help, but I need new eyes on this.
So far the car idles and I can drive it on the dyno, but when I hit the pedal the tb only goes to 50% opening. I'm attaching the tune file and log. Thank you in advance for your help!

Driver demand is stock, Torque tables/inverse tables are skuffed. SD needs work. You still have the IMRCs? I would probably lock them open and simplify your tune that way. Search for a Roush tune on here it will give you a good idea on what everything should look like. You're building boost then hitting a torque request limit because your torque tables are still somewhat stock. Changing the axis numbers isn't good enough. Need to actually change the torque numbers...
You need a good base tune to start
