Dyno test: K&N Intake with/without tune
So today I had a chance to throw the car on a buddy's dyno. Car is stock except for a K&N intake. Keep in mind, this dyno (dyno dynamics) reads notoriously low, about 20% lower than a dynojet or dynapack.
The comparison here is the stock tune with the intake vs the Superchips "91 Perf K&N Intake" tune.

Not much change in the low end, but around 4200 the tune starts to show and carries power much better than stock up until 5900. You can see how much further the Superchips lets the car rev, although it doesn't make any more power past there. We also tried removing the filter altogether (no graph, sorry) and the car picked up ~10whp/tq in the midrange with zero peak gain. I know the K&N isnt the best but it came on the car when I bought it *shrug* it works for now! Next time I hit the dyno it will be with a solo catback and SLP underdrive pulley.
