Default 2009 XF s/c STOCK rwhp?
Has anyone had their stock 09 s/c xf dyno'd? I'm going to get mine done soon, but it's after Mina exhaust and 2.5 pulley w K&N filters. Wish I did it prior to upgrades to see the difference.

I would think they would be similar to the STR, so in the 330-340whp range.

Based on the STR numbers posted we should be in the 352whp range if we had a similar transmission loss (16.3%). It can vary wildly depending on the dyno as well.
