Depending on the dyno used you'll see anywhere from 300 to 350lbft at the wheels with just a tune.
My car will spin the fronts from 15 to 50mph with a 2nd gear roll on. destroys the tires as soon as it hits.
For that kind of torque it needs more tire and stiffer mounts.
RMM is a must, even if the TSB was done or not you can still get the bang and loads of wheelhop
