BOOST issues. Any advice gratefully received.

AJP:
Fingers crossed for you pal. All I'd advise is don't go to R-Tech unless you're 100% happy you've ironed everything out.

I was due down there last month for a tweak up to Stage 2 after having a full Powervalve fitted. What happened in reality is that the extra torque from the exhaust finally pushed the clutch over the edge. So I've had to cancel R-Tech, and I should be collecting my Helix Organic clutch and new dmf tomorrow! Will get that fitted asap...

And I'm seriously considering a Loba pump myself before I book back in at R-Tech, as I'll then have a clutch that's good for 400lb/ft. Although I know it's 500 notes I should be putting towards a BBK instead!

MS1:
Yeah you're absolutely right. I don't want to rock up there if it's going to be a waste of everyone's time. Even though I'm desperate for a stage 3 tune. Thanks for the kind words and good wishes mate. I'm just hoping it's a f*cked DV or split pipe or something.

MS1:
I seem to be getting full boost for a second or two, then half boost, then no boost, then three quarters boost. It's just all over the place. Got the car scanned on Delphi this am. No faults, all well apart from the wastegate function being like 40-75% and intermittent. But truth be told, I don't know what that means anyway. It has to be a boost leak, can't be PCV as I have a BSH PCV Kit. Can't be turbo back, or I wouldn't get severe boost loss. So here's to productive smoke tests!

AJP:
I might be wrong but I'm sure sporadic wastegate values would point to the N75, although you've got a new one...? Strange.

There are quite a few components that can fail intermittently without giving a fault code. MAF certainly being an obvious one.

One of the downsides to getting loads of parts changed in one go like you have is that it's difficult to narrow down the culprit quickly if things go wrong! Without a code it's just a case of old fashioned process of elimination.

You say Stage 3 by the way, am I right in saying that includes a turbo upgrade?

I don't mean to scaremonger, but have a read through this old thread from Redrobin, if you've swapped out all the usual suspects

Hopefully it's not as serious and the smoke test will show up a simple fix  :happy2:
