03 Where it breaks first
Stock IS38 is done around here — hybrid turbo plus fueling is the next chapter.
Haldex needs regular service or it cooks and quietly stops sending power rearward.
04 The typical path

Stage 1 tune → intake → downpipe → intercooler → Stage 2 tune. Fueling before E85, driveline before sticky tires.
