This guide covers the tuning options for Part 37 in Need for Speed Underground 2, focusing on Turbo, Nitro, Suspension, Drivetrain, and Aerodynamics.

Turbo: Torque should be high at high RPMs (starting around 4000-5000 RPM). RPM Ranges and Torque: 0-1: Nothing 1-2: Nothing 2-3.1: 10-15 3.1-4.3: 28-30 4.3-5.4: 40-45 5.4-6.5: 73-78 6.5-7.6: Maximum 7.6-8.8: Maximum 8.8-10: 73-78

Nitro: This upgrade is available but not recommended for use.

Suspension: Lower the car as much as possible for better aerodynamics. Use Hard Springs, Hard Shocks, Soft Sway Bars, and a More Steering Ratio. Suspension Settings: Front Lowering (in): -1.30 Rear Lowering (in): -1.29 Front Springs: 9.95 Rear Springs: 9.95 Front Shocks: 10.00 Rear Shocks: 10.00 Front Sway Bar: 0.02 Rear Sway Bar: 0.00 Steering Ratio: 1.10

Drivetrain: Prioritize Acceleration over Top Speed, as most races don't allow reaching maximum speed. Set gearboxes to be sequential for better acceleration. The specific gear ratios depend on your car's Top Speed. Gear Ratios (MPH): 1st Gear: 43.1 2nd Gear: 68.8 3rd Gear: 99.1 4th Gear: 119.0 5th Gear: 149.7 6th Gear: 174.4 Final Drive Ratio: 4.80

Aerodynamics: Both Downforces should be set strong. These settings affect track performance more than Dyno runs.
