New here - E46 330ci owner from Germany

Welcome! The E46 330ci is one of the best BMWs ever made. For stage 1 on the M54 engine, the gains are modest (maybe 10-15hp) since its naturally aspirated. But a good intake, exhaust, and tune together can make it feel much more alive. The real magic with E46s is in the handling - suspension upgrades make a huge difference.
