CJD Special Tunes 3.8

Fixed:
- Sunburst V6 engine no longer breaks on spawn
- updated the grand marshal

Added:
- CJD performance intakes for multiple vehicles that allow for use of my other intakes where they were previously unavailable
- Ultra heavy duty engine blocks to support my performance intake
- Twincharger for 1.6L I4 rally engine
- CJD Special preset for the bluebuck with hydraulic suspension

Changes:
- Updated sounds for the 2.0L I4 should sound much better now
- Updated the CJD Performance exhaust for most vehicles, should also sound much better
- Engine blocks for the 427/350 V8 now change the way the engine sounds
- Re-tuned suspension for sunburst, moonhawk and miramar
