i was swapping my newly rewrapped steering 2 days ago... and to my horror, the Air Bag light at the dash suddenly came up blinking... checked every single connection and i am very sure i didnt break anything...
1. Boost comes in very very early at around 2000rpm and peaks very quick by 2500rpm.
2. Once boost is in the car jerks pretty dramatic.
3. Idle is fine at around 850rpm.
4. Timing check is on the dot...
