12gauge82 Posted June 17, 2022 Report Share Posted June 17, 2022 No experience or expertise, but there's an old saying. If it sounds too good to be true, it probably is. Quote Link to comment Share on other sites More sharing options...
B391 Posted June 17, 2022 Report Share Posted June 17, 2022 Looked into this before. My advice would be a light foot, easy acceleration, read the road and cruise, not push. That will save IMHO more than any gizzmo can. Quote Link to comment Share on other sites More sharing options...
snow white Posted June 18, 2022 Report Share Posted June 18, 2022 I have had my Nissan NP300 remapped I could not notice any difference to be honest I have fitted a Evc control all it does is takes out the peddle lag so more responsive to pulling away as for saving fuel it will take a long time for me to get my money back all I can say the choice is yours Quote Link to comment Share on other sites More sharing options...
Lloyd90 Posted June 18, 2022 Report Share Posted June 18, 2022 It makes you think why the people making the cars don’t do the stuff these external people claim they can do? 🤷♂️ Quote Link to comment Share on other sites More sharing options...

JohnfromUK Posted June 18, 2022 Report Share Posted June 18, 2022 I had my 200TDi Defender upgraded (larger intercooler and tweaked boost and injection pump) by Allard many years ago. It has two 'modes', power increase and 'normal'. Power increase does work and takes it roughly to the output level of the same engine is Discovery auto tune state (about 20% increase), but I suspect makes it thirsty as it is a bit 'sooty' when selected, so largely unused. In 'normal', the bigger intercooler gives better breathing and better cooling of the inlet air with claimed benefits of cooler running and better economy and drive-ability. The improvement in economy is fairly slight, but on a long run probably gives about 10% improvement. I can't really comment on cooler running as it was never a problem, but roughly 25 years use and never needed any unscheduled engine attention is a good indicator that all is well. Others regular Defender drivers have commented it has better flexibility, but as I drive no other similar vehicles - I can't say I notice it. Overall - it has been good and since I can't remember what it cost to do - I have no idea if it saves much! Quote Link to comment Share on other sites More sharing options...
scarecrow243 Posted June 18, 2022 Report Share Posted June 18, 2022 most of these cost a fortune with little or no saving years ago they had a water system the injected water into the cylinders it also claimed to save on fuel etc all it really did was kept the top of the piston clean Quote Link to comment Share on other sites More sharing options...
