The above article has the before and after Roushcharger dyno graphs several people asked about!

 

Looks great Ken! Did you use an XCal2 or anything on the truck, or is that on stock tuning?

 

That is stock Roushcharger tuning.

Stay tuned... (no pun intended) there will be another article soon with more dyno charts, before and after custom tuning.

 

Well... hurry up...

What type of dyno did you do this on?

 

A Dynojet 224LxC

 

Nice numbers Ken, especially for a 4x4. I like that the torque curve is nice and flat.

I don't know what the A/F ratios were or spark advance, but I'm going to take a wild guess and say 375hp/430tq at the wheels.

 

Roush has good air/fuel ratios in their tune. It'll start out rich but adaptive take it right to where it needs to be really quick. A/F doesn't need to be address by anyone doing a custom tune with a Roush... Roush has it nailed.
