Stock RWHP of 05 5.4

Just doing some playing tonight. Just curious what the rwhp numbers most people get with a 05+ Superduty with a 5.4 and an auto are. Stock and tuned would be great.

Bill, can you remember what you got the last time you did any dyno testing on these?

Oh... something like this:

Hope this helps.

Cool. I need to find that extra horsepower on the big end then. The truck is an 05 F250, are the 5.4's the same as the 150's?

Dang it, I thought I nailed this one first session.

John,

They're pretty similar in configuration and power levels should be close. Your dyno runs look pretty nice. 35HP on the aggressive program is about right for most applications. That's what we advertise for the canned tuning on a bone stock truck so you're doing just fine.

Some airbox modifications will help. Removing the snorkel from the fender is usually good for 5-8 HP.

Take care.

Thanks. I had a good teacher.
