Hire a professional for complex modifications requiring specialized knowledge, such as ECU tuning, turbo installations, and forced induction systems. Professional services offer warranties, time efficiency, and expertise. DIY approaches work well for simple modifications like air filters, exhaust systems, and basic suspension upgrades, provided you have proper tools and safety knowledge.
What common mistakes should I avoid when tuning my car?
Avoid over-modifying without proper support, such as increasing power without upgrading engine internals or fuel systems. Don’t skip engine management systems or professional inspections. Always follow a sequential modification approach for compatibility. Research local regulations for legal compliance, disclose modifications to insurance providers, and document all changes to prevent costly mistakes and maintain modification records.
