does anyone know how there tune differs from the Penner tune?, i'm currently running Penners with the speed limiter removed, and has anyone been able to find the micron filter rating between a stock air filer and the DNA filer, I haven't been able to find that yet
Ah, snow, shmow! Don't be a baby, what's the worst that can happen?!? Go ride! I ride whole winter, never stop. You can too, you just need to choose to. Now, let us hold hands, repeat after me, I want to go ride! Say it like you mean it! Louder!!! Who wants to ride? You want to go ride! Now go ride!!!
If I remember right, V-Steel did a little research on the stock filter and either a K&N or DNA. The result was the stock filter breathes more than is needed by the engine. He decided not to change it for our Bonneville Record runs.
