H&S Performance - World's first 500+hp LML Duramax!

We've been making some great progress on our 2011 LML tuning so here's a quick video showing some clean raw power!

This run was done in 5th gear with the torque converter locked on our Mustang 1100 SE Dyno. The only performance modifications are a downpipe-back exhaust system and H&S tuning.

It made 507.8 HP and 1008.3 TQ uncorrected which makes it the world's first (known) 500+whp LML Duramax! This truck previously made 360 HP and 671 TQ in stock form on the same dyno.

Dyno graphs can be viewed here:

We are hoping to release our LML tuning to the public early in March.

Thanks to everyone that participated in our "Guess The Power" giveaway on facebook and congratulations to the winner of a new XRT Pro!

Thanks for watching and stay tuned for updates!
