The engine is tune controlled by an ECU (computer) and is fed info from over 8 different sensors.

Tuning an engine is not like the old days; a scan tool is needed and we have 3 different types to cover all the range.

• Spark plugs last 40,000 up to 150,000 depending on the type, but still need checked
• The fuel filter needs checking and replacing more regular these days
• All air filters are smaller and finer and needs replacing more frequently
• The air intake has a sensor that needs cleaning to maintain the fuel economy
• The computer has a history bank that stores all codes current and old, we check all of this when your car is in for a service and reset if necessary
• Tappet (valve) clearance checks are becoming less but still need checking
• We will check your engine for vacuum leaks
• The exhaust system will be inspected for leaks
