Here's your condensed Boost Builder guide...
1.) At the line, foot on the floor...
- 2-Step is engaged at much lower RPM than normal
- Sparks are skipped, raw fuel burns in exhaust
- Turbo spins, builds manifold pressure
2.) Repeat step #1 at higher MAP/RPM values until final programmed boost setpoint is reached.
3.) Stay on 2-Step until it's turned off and car launches. Total elapsed time = about 1/4 sec.
