Carb vs EFI — Which Should You Choose? 🤔

Both setups perform well — the right choice depends on how much tuning you want to deal with.

• 🔥 PWK Carb: Lower cost, simple, and widely understood. Requires tuning based on elevation and weather.
• ⚡ EFI: Higher cost, but starts instantly, self-adjusts fueling, and runs smoother with no carb tuning.

At higher elevations: EFI is significantly easier to live with since it automatically compensates for air density.

Carb = hands-on. EFI = set it and forget it 💨
