And thanks to all others who have posted with some great advice and tips, as Racerx said about the clever people on this site, we are indeed lucky to have such a valuable pool of knowledge from the members of this forum

[Racerx]

Good luck with it, interested to see how you go.

It may be a melted/blocked catalytic converter, I've got her booked in tomorrow at an exhaust place for a heat test.

my ute had the same problem as ravenhard had.

[bluesmuso]

Yeah, the tuner is going to look at that next week, it is more than likely a wastegate flapper valve issue, I just want to rule out the catalytic converter first as I believe it is a pretty straight forward heat test to determine if there is too much heat in front of the cat and too little behind indicating an internally melted cat.

[bluesmuso]

Cat is fine, nothing wrong with it.

[Racerx]

that's one thing eliminated at least, it all seems to be pointing towards the wastegate. When are you getting it to the tuner?

[bluesmuso]

Neville from Speciality tuning at Marion is looking at it Thurs, I can't get into graham west workshops until later next week, speciality tuning is within walking distance of my work so it is easier, and he has a dyno.

It does seem to be pointing towards the wastegate, there is also a trans cooler mounted in front against the intercooler (not the best spot) but unless some intercooler pipes have been blocked or something I doubt that would have anything to do with the power loss and dreadful fuel consumption.

Totally unrelated but It also (as I found out today when some moron changed lanes without looking and almost hit my car) has a very very quiet horn, infact unless you were standing with your head under the bonnet you wouldn't hear it LOL

I've heard of horns not working at all, but too quiet? Maybe it's full of water, I laugh every time I sound the horn.

Sorry about the change of subject but I'll have to fix that bloody horn it sounds ridiculous.

Anyway back on track, I'll keep you posted after my results from speciality tuning.

the horn may have been moved when they installed the trans cooler or the intercooler. I know I had to move my horn when I instaled my RAP1D cooler to under the drivers side headlight due to being no room at all when you install a large cooler. So if its been moved it could be loose or have a bad earth. I actually took 1 horn off the bracket and run only 1 horn instead of 2 but is plenty loud enough.

[bluesmuso]

Yeah, mine sounds like a duck on acid, might have water damage, was probabl moved and not earthed properly and I think only one is working (there is two right) the cops might nab me for it so I'd better fix it, hope I don't have to take off the front bumper to get to them.
