The car companies can talk about close production tolerances all the want, the the power out puts are all over the place. I have dyno tested bone stock LS1 GM cars from 275 rwhp to 349. LT1 cars from 225 rwhp to 302. Have seen virgin A4 LS1 cars run everything from 14.20s to 12.80s here at Tulsa. One freak bone stock manual trans 2000 Camaro SS (except the PCM tuning) makes 349 rwhp and runs 12.30s. I have a customer in Houston that ran 11.55 with his A4 2002 TA, never had a valve cover off. But, some won't even go 13s. I don't doubt Ford and MOPAR are the same way.
