Our Tuning process enhances and optimises the power of the engine within safe limits, not beyond them. Extra power will also result in fewer gear changes, which might actually reduce overall wear & tear. Manufacturers have to build in a tolerance for the parts in the engine, to manage the effect of wear and tear, production variations, and to ensure their warranty claims during their warranty period normally 3 years, are kept to a minimum.
Most race and rally engines are pushed for every last bhp, and thus they more common to fail, whilst normal car/van/lorry engines are limited back, well away from probability of multiple failures. Each individual engine is different as in how much it can be pushed in a tuning, but a good tuning from a quality tuner like Auto Tuners will never get close the limits of component failure.
You will see that the top companies within the market place have all develop vehicle improvements to similar outputs. Beware of tuners who claim significantly more, itís either lies hoping that the average customer wouldnít be able to tell the difference
