Performance Optimization and Speed Unlimiter for all Land Rover Td4 2.4 A well-balanced tuning for your Defender Td4 2.4 - model year 2007-2011, which gets dormant power reserves out of the Puma / TdCi engine without damaging it. In contrast to many others, this tuning does not focus on a maximum increase in power, but instead achieves an engine-friendly and at the same time clearly noticeable increase in horsepower and torque. By reprogramming the control unit, the factory maximum speed / VMax restriction is also completely removed at the same time, allowing the engine to develop its full power spectrum - this is useful for frequent motorway trips, for example. Optionally, the exhaust gas recirculation (EGR) can also be switched off - this improves the engine's pulling power. Please note that the EGR valve must not be dismantled, otherwise error codes will be generated. Our software-based deactivation, on the other hand, does not trigger such codes and can, of course, be retrofitted without leaving a trace - this applies to all tuning measures offered here. The configuration is done according to the customer's wishes - in case of special requirements: Just contact us! Possible configurations are: no power increase, deactivation of exhaust gas recirculation no power increase, deactivation of cruise control no power increase, deactivation of exhaust gas recirculation & deactivation of speed limiter power increase to 114 KW/155 PS at 420 Nm, incl. deactivation of speed limiter power increase to 114 KW/155 PS at 420 Nm, incl. cancellation of cruise control and deactivation of exhaust gas recirculation power upgrade to 129 KW/175 PS at 440 Nm, incl. speed limiter cancellation, exhaust gas recirculation cut-off and larger intercooler. The price of the 175 HP tuning already includes the larger intercooler. We do not offer it without it, as this would put too much thermal load on the engine. Only for motorsport applications, no road approval! We recommend reinforced silicone hoses & K&N exchange filters for tuning: Order silicone hoses here / Order exchange filters here. The tuning can either be carried out at our premises by appointment, or you can send us your engine control unit and receive it back in the shortest possible time with the performance-enhanced programming (and possibly the larger intercooler for self-installation). We offer the following flat rates for the installation of the intercooler: Vehicles without air conditioning Vehicles with air conditioning Please select the desired tuning variant. After ordering, one of our employees will contact you to arrange an appointment, so please be sure to include your telephone number with your order. Please order in good time, we have approx. 4 weeks lead time for workshop appointments. Assembly is only possible on site in Berg near Neumarkt (postcode: 92348).
