Yeah Maf mate.I.disconnected mine and the car still runs the.same makes no.difference if it's connected or not

[threedogs]

I disconnected the boost sensor when I changed my IC,, drove home not knowing,
made no difference whats so ever,

[dirtygu]

Hmmmm does it mean.it's dirty.or.is.it broken what else can.make the car loose.power at about 3000Rpm but boost goes up car just hesitates

Got 2 going on the one thread, first @ Hodge this gave mine a pituu sound you can see the crap weld the guy did at the exhaust place failed next to the weld on the dump pipe
@ dirtygu by afm do you mean Air flow meter. OR MAF as we call it ,
spray heaps with MAF cleaner from Super cheap allow to dry and re-install.
Again only do one thing at a time that way you'll know what it is, by doing two you'll never know what the problem was

Thanks td. I checked and re-checked all of that. Mine is a brand new dump pipe, came with the beaudesert exhaust, but mine's been doing it even before the exhaust upgrade, so it's something else.

Ok so I cleaned my maf today but the cars still the same would anything else make it loose power but not throw the engine light uo

I'm out of ideas, TEST 1 disconnect the battery for 1 hr.
if it runs ok till you put your foot down ,its going into limp mode,

You'll need to fit a dawes valve, You could hook up a temporary boost gauge to set

[dirtygu]

Thanks td I have been reading on some overseas forums n they say to get it out of limp ya have to connect it to a a scan tool is this true its like I have the symptoms of limp mode as I think it over boosted on the freeway but when I put my foot of the pedal then back on it didnt come back on the gas still just hessitated

[threedogs]

You said engine light a few posts back that suggests a blocked fuel system or dirty fuel filter.
Disconnecting the battery should be enough to re-set the ECU and there fore limp mode.

[dirtygu]

Engine light was I had a blow fuse for the egr that I needed to replace done that but it is still kinda in limp mode

[dirtygu]

Ok have had a closer look at the car it has a small amount of white grey smoke what could that be also still have the non power over 3k rpm
