⚑The IS20 is maxed around the APR stage-2 rating (337 hp); the IS38 swap is the natural next step, and it wants an HPFP with it.
⚑Water pump and carbon cleaning are when-not-if services on the EA888 (community consensus). Budget them into the build.
04 The typical path
Stage 1 tune → intake → downpipe → intercooler → Stage 2 tune. Fueling before E85; the clutch on a manual, a gearbox calibration on a dual-clutch before sticky tires.
