We are an automotive tuning company based in Andover, Hampshire offering remapping, diagnostics, DPF and EGR solutions and more to this and surrounding areas.
We are an authorised agent of Avon Tuning offering a premium file tuning service at very competative prices.
As this is a computer modification we believe only the best tools, files and staff are what our customers deserve and because of this we ensure every tune is carried out with the utmost care and to the highest of standards. All vehicles have a full diagnostic and performance log carried out before a tune and the tune is then tested in full once uploaded. We are certain that every car tuned by Test Valley Tuning has been looked after and treated like it was one of our own.
