Diagnostics First

Every Remap Starts With A Diagnostic Check

Before we touch a single map, we run a full system scan. Boosted boost figures on a faulty engine is a recipe for expensive problems — so we always check sensor data, fault codes, boost leaks and DPF/EGR health first.

  • Read & clear fault codes from every ECU module
  • Live sensor data review (boost, lambda, EGT, DPF pressure)
  • DPF & EGR health check on diesel vehicles
  • Battery, alternator and starter test before remap
  • Pre and post-remap logs saved with your vehicle file
