Go See Tony at Tuners Inc and have him tune that thing for running some Sunoco 105 octane.

With gas prices being where they are now I bet the Sunoco 105 is about $9.00 a gallon. The last time I bought some it was about $7.50 a gallon.
 
My v8 stang is about to get it. My v6 had high miles and ran like **** when I got it. I changed the plugs it ran a lot better. I also cleaned the throttle body. But honestly It actually ran better after I sea-foamed it. If you have questions theres many forums dedicated to it. Heres the HOW TO

Also make sure you do it like he does it in the video. Pick that vaccuum line other people have tried going through the IAC valve and that's pretty dumb in my opinion but who knows.
 
No, not really, seafoam is supposed to clean the buildup on older marine engines and isn't necessary on a properly maintained engine. It definitely can help, though probably won't do much on a new engine. Things to look at/replace:

spark plugs
fuel filter
air filter
coolant
serpentine belt
clean injectors
COP boots and springs
 
Ahh if it's a new engine not so much I guess. I know a guy that had a brand new 99 mustang gt that his family bought and garaged it. It sat for probably 9 years. They seafoamed it even though it was brand new and it seemed to do that new engine great. (the engine had been driven the 10xxx mile breakin point or whatever though im assuming)

Already have new spark plugs, coolant, serpentine belt, and cleaned the injectors.
Isn't the fuel filter a pain in the ass to change?
