The G6Et That Couldn't

[CLuTZ]

I'd change the injectors, just to be sure.

I was just about to post

Diff bushes recently replaced.

Indicator Fluid just fine.

Muffler Bearings, def muffler bearings.

18psi 288rwks is a lot boost mate.. should be more like 13 to 14psi for that power..

[old_mate]

Where it falls over the little turbo is only making 14psi.

I be looking at a set fg f6 injectors to be on the safe side mate. your injectors would be maxing out..

[thatguy]

What size are stock injectors. Looks like an exhaust restriction to me.....cat blocked?

Holy s@#t, I hope ( sought of ) that there is an easy fix problem with this, looking to get my car tuned very soon with Clinton and I was hopeing for around 300-305rwkw. Mate as said here I would check the exhaust I would think that Clinton could tell whether the injectors are the problem while tuning it, but I could be wrong.

Clinton is from what I've heard pretty swithed on with these cars,so if he thinks its the vavle springs then I would probably be inclined to go with him on it, the other thing is of course he was there and non of us were, this is why I say maybe listen to him.that's not to say that the suggestions here arn't good ones, they are, just we are all guessing he had it in front of him on a dyno.

I hope what ever it is it's an easy fix.

Good luck mate.

We didn't have much time to troubleshoot. I have confirmed with him though its got plenty of fuel, so its either the springs as we suspect or the cat. I am pretty sure its not the cat because its only twelve months old and clinton didn't mention it but is there a quick way I can check?

We will know soon enough. I'm pricing up some springs as we speak.

[jimmixr]

valve springs would give it a rough idle after a power run.. lifters pump up then bleed down and idle settles.

Id be leaning towards the cat, sounds like a blockage.. less flow through the cat would restrict your boost.

But in saying that its probabaly a good idea to do the springs.. future proofs it.

[matsfgxr6turbo]

wouldn't valve springs give it a hump in the power curve as the springs bind then unbind the curve looks nice and smooth so I would think a rooted cat is more likely?
