What Owners Say
Owners and enthusiasts consistently note the DW400's ability to fix fuel pressure fluctuations and smooth out acceleration issues, particularly when upgrading to E85 or targeting 500-650whp builds. The pump frequently appears in tuning discussions alongside the Walbro 450 as a go-to upgrade for serious power levels. However, some controversy exists around reliability, with mentions of DeatschWerks pumps "crapping out" and debates about whether certain tuners will work with them. Users acknowledge these pumps typically run at low duty cycles rather than continuous high output in real-world conditions. Despite the mixed reliability feedback, the DW400 remains a widely recommended option for enthusiasts pushing significant horsepower on ethanol blends.
