Gotcha. Any idea what they're putting to the wheels, stock?

My dad has an 06 6MT and it feels like it could use a bit more high end. I had it for a few days when he borrowed my truck and the clutch and shifter took me a while to get used to.

 

thats because there is no clutch fork

what engine is your '06? mine is '07 so its "306hp" vq35hr. it should be around 245-250whp/210-215tqe stock but curves are completely different from mine

 

the hr is so much better than the revup and older engines they cant even be compared.
