Have tuned a few turbos but I now have a 5.4L and I'm keen to get it going a little better. I know a Barra fairly well but not these. Any one done some work or tunes and is willing to help me. Car has middle muffler delete, K&n filter and underdrive! Goes like a slug :/
Like any car, especially naturally aspirated, you want to rely on bolt on mods to give you power potential...and then tune to suit. I personally don't bother with NA V8's with few mods.
Yeah the thing is legit a slug! For a big motor is has no balls! Was hoping someone here has dealt with them and could offer pointers! Seems like at the current stage there's not a real lot of gains to be had
I wouldn't bother, you barely feel the difference. If anything, tune the gearbox if it's auto.
As Toads has said when it's a tune only there's not a massive amount of gains as the platform is "all motor" but couple it up with some mods and they are a decent drive the 5.4, will never be as appealing as a boosted 6 but if you're familiar with N/A V8's then they hold their own modded no worries
I've done a few now and the biggest jump from stock is obviously intake and full exhaust coupled up with a tune
This is a before and after ( completely stock to K&N and extractors/cats/twin2.5 & tune ) and it doesn't look much but the drive is night and day ;) it's manual

I've been told that changing the cam sprockets makes them feel fairly lively, but can be fairly expensive too?
