Pre-tuning checks

Having your car in excellent running condition is very important before tuning. Sparks plugs should be replaced if they have more than 15k miles on them. All plugs should be checked, and gapped to .026-.028" before tuning. Be sure the vehicle is free of any boost leaks, fluid leaks, or exhaust leaks. If hardware issues are present it will delay the tuning process and also potentially put your engine at risk.
