BMW Z8 Gets More Power After Stage 2 Tuning, Custom Exhaust

UK aftermarket shop Evolve Automotive worked on a customer’s BMW Z8 earlier this year and extracted 92 horsepower after repairing and tuning its S62 engine. They managed to squeeze out nearly 441 hp after noticing one of the cylinders was misfiring before giving the naturally aspirated V8 a stage 2 upgrade.
