VY Commodore S Ute series 1
G'day, got an issue with my VY UTE S pack where I am losing acceleration at 60kph.
I've replaced plugs,leads,coils,refurbed injectors, air filter meter,fuel filter and air filter. As I'm driving, when trying to put my foot down it gives me nothing. I've had the trans checked and ok'd, cat has been checked too.
Doesn't appear to be any air leaks either.
Been scanned and no error codes come up.
I'm at a loss here.

fuel pressure? stick a fuel pressure gauge on it and go for a drive see if it drops off.

If v6 did you replace the dfi & check the wiring that goes to the dfi plug?

Might have to bite the bullet and book it in mate. Sounding like you have already thrown some parts at it, and could throw in some more and still not figure it out. These sorts of problems are often not easily sorted over the net.
