I have an Xcal3 now, downloaded the Roush tune and then put it back on, would that make a difference.

LOL, take it to a reputable tuner. This is starting to sound like a scam. I have experience with RWTD, they were great. Stop wasting the owners (and your) time and money, this is just rediculous.

Ahh, yes, this was all just made clear to me. Thanks ozws6!

I will point my friend who has the software here and see if you he can tell you more. I am just the guy getting tuned and trying to learn as much as I can, these F150's are new for both of us. The...

Hello,

Can anyone tell us what the MBT spark is on these 5.4L?

We were messing with timing this weekend and found these engines love octane and can adjust timing accordingly. What we don't...
