03 Where it breaks first
K04 territory. Past ~350 the rods and HPFP become the honest conversation.
EA113: check cam follower wear. Early EA888: timing chain tensioner. Both are cheap checks and expensive failures.
04 The typical path
Stage 1 tune → intake → downpipe → intercooler → Stage 2 tune. Fueling before E85, driveline before sticky tires.
