It depends on how well the car is tuned. I did a BPU job here on a 98 quicksilver with only 5300 mile on it. He went to the dyno and put down 360rhwp. Found out he was running very rich. He picked up an AFC and I tuned the car with a wideband O2 sensor. He pulled 400 rwhp and 405 tq. Big difference.
