03 Where it breaks first
Heat exchangers come first on the VR30: it pulls timing from heat soak long before parts break.
Young aftermarket. Flex-fuel kits and proven tunes only; the platform punishes experiments.
04 The typical path
Stage 1 tune → intake → downpipe → intercooler → Stage 2 tune. Fueling before E85, driveline before sticky tires.
