One of Tunex's specialties is analysis of Basic Engine Performance.
    When a car enters the Tunex service center it undergoes a complete performance and visual analysis.

    The Basic Engine Analysis includes

    A visual check of the components under the hood, Electronic check of ignition system,timing controls and cylinder efficiency, gas analysis of the emissions and a computer check for trouble codes.

    This in-depth procedure determines the problem areas. A complete written quote is prepared and reviewed with the customer and only authorized service and repairs are performed with top quality parts.
