Hey Brendan,
You asked which tuner I used? Silverwater Automotive Services.
That was my mechanics preference since he built motor. They seemed to do a decent job, car drives nice off boost etc.

brendan is the boost controller getting its signal from the compressor housing or the inlet manifold?

sorry i didnt reply to your sms. im sure you can get this sorted out somewhere closer to you.

No prob Trav. I think the boost con. is getting its signal from the inlet manifold from memory.

Can anyone tell me what the barb/nipple shown below is connected to? The hose that is supposed to connect t o this barb/nipple is already connected, and all I have to do is fit it onto this barb/nipple, but I just wanna know where the hose goes to:

What the! That power figure is low. 680cc injectors at that duty should be in the realm of 220kw minimum. Why so much fuel for smallish turbo on 14psi? *blink*

Was that hose disconnected at time of tune? that would explain everything... massive boost leak.

There is meant to be a hose between that barb and a black steel pipe in the direction it is pointing.

If that hose was off during the tune, do -not- drive car under boost with the hose connected until a retune is done.

I assume it may have been disconnected when the pipe was removed for your dump pipe work/coating?

Call or email if I can help further. Forum browsing is not something I have the luxury of doing so often.

^What he said!
Hopefully that's all that was missed before the tune [B)]

Thanks for the confirmation and advice Tristan. Really makes me feel more confident about my expectations.

Yes, that hose was disconnected at the time of the tune. And you are very likely correct that it was removed when I took off the dump pipe for the thermal coating. The only person I can blame for that is myself (aka NFI Auto), since I must have either not connected the hose back at all, or not clamped it down properly such that it slipped off some time later.

It was unfortunate that the tuner did not pick this up. I did leave him my mobile so that he could call me if there were any problems while tuning the car, but I guess he didn't see my car not being able to achieve 18 psi as a problem.

If that disconnected hose can be confirmed as the problem, then it's an easy fix. Thanks for the advice not to drive the car under boost with the hose connected. To be safe, I will drive the car with the hose remaining dis-connected until I can get it re-tuned.

THat's the a/c idle up valve. We did unplug that when we took the dump off. Looks like you forgot to put it back on when u got it all back though =/

I'm glad to hear it's something as simple as a disconnected hose. I look forward to your next tune and what numbers your car produces. Good luck man.

NFI Auto FTW! We had a big week it seems. Look on the bright side, at least your car didn't electricute you & almost catch fire on the highway like mine did a few days ago.....hahahaha!

You bringing your car to the next meet? Haven't seen you in ages dude.

How'd your car catch on fire man?

Yeah I'll be at the next week. I get back from holiday just 2 days before the next meet so I should still be in holiday mood.
