1987 Buick Grand National 1.0

My replica of the '87 Buick GN

3.8L turbocharged-V6 - 245HP
4-speed automatic

Tried my best to be as accurate as possible with specs/gear ratios and stuff like that but there will probably be inaccuracies here and there, starting with the fact that it has a single exhaust instead of dual (didn't have the dual exhaust option in automation).

Also, no matter how many times I go back into automation to make sure all the lights are appropriately set (headlights, indicators, tailights etc.) I still have some of the brake lights/indicators come on as headlights, so there's that... anyone know how to fix this?
