Have been running steinbauer chip for 5 yr set to max 130% ,made a small amount of difference but noticeable on hills . Recently 18 months ago installed a no limit chip as well this made a huge difference set @10 out of 12 ,more so than steinbauer $1300 vs $150 .@110kph egt stays at 400-450 c pre turbo with both chips running .boost max is 24.5 psi .haven't had it dynoed .But have set no limit to higher setting but it made the truck a bitch as the accelerator got really touchy to the point where you could feel cruise control comming on/off the pedal .Also have followin mods map sensor resistor ,egr blocked ,cat removed & free flow muffler ,450x300x100 core intercooler and hardpipes ,airbox muffler removed 90mm pipe to snorkel ,bullbar ,winch, 3.5" lift
With 32" tyres I averaged 12-14 L/per 100k
Would like to get ecu tuned instead of the chips as the chips can only increase fuel
Pressure and extend injector trimming , and some boost
Also have driven a v6 diesel d40 (standard) recently and mine goes the same if not better even with the bigger tyres and accessories
