Holy. Shit. This thing pulls hard.
Main increase was from around 2.5 to 5.5K RPM, At first it wasn't that noticeable and I wondered if it was even working but then after a few pulls it started adapting and then pulled way harder. Doesn't matter which speed you're at, you'll be shoved in the seat when you kickdown. Can't wait to drive it some more.
Not bad at all for 250 (+ 80 installation) CAD for a used Stage 1
Here's the vid, had a slight wheel spin as i'm on skinny winters
