However, on some older vehicles a wire-in harness might be needed. RELATED: The Best Fuel Injector Cleaners Plug and Playīoth these chips simply take advantage of existing plugs and connections and require no modifications at all. The Steinbauer chip doesn’t make changes to the common rail fuel pressure, which should maintain injector and engine reliability. What both chips don’t touch or adjust is what’s important here turbo boost pressure remains the same, with adjustments only made around fuel injection duration. Engine protectionĭP Chip and Steinbauer claim all engine systems are monitored in real time to ensure the increased performance parameters never exceed what is considered safe for a standard engine. Consider that improved fuel economy is a pleasant surprise rather than a guarantee.

Not only that, more fuel is required to make more power to start with, so vehicle-specific components like gearboxes and transmissions also play a big part in any fuel savings and these vary greatly.īoth the Steinbauer chip and DP Chip are, first and foremost, performance modifications so the tuning is tailored mostly towards drivability and improving power and torque delivery. While Steinbauer and DP Chip say an improvement in fuel economy for any vehicle is achieved (both claim a potentially optimistic 10% for some models), this comes with a few caveats a vehicle that is more fun to drive often encourages more spirited driving, taking away those incremental gains. To really see the improvements, a dyno run before and after will validate claims and reassure your money is well spent.

Not needing to touch injectors, exhaust, or the ECU itself to find improvements makes this hugely appealing.īetter performance means better towing and overtaking ability, two important considerations for modifying your car or 4×4 in the first place. We will talk more about how this is achieved later on, but it is mostly due to increasing the fuel injection duration. Key Similarities Performance improvementsīoth the Steinbauer performance chip and DP Chip make big claims about the increase in power and torque as much as 25% more power and 35% more torque over a standard engine.
