Not quite the same vehicle but my old T4 van wouldn't make full boost, spent ages fiddling around trying to work it out.

Ended up being a collapsed cat in exhaust.

She's not holding full boost at the moment. Going back in shortly to check for leaks. Could also be a failed cat in the exhaust?

Jon, are you going to gut the cat and reinstal or replace it with something else?

If the cat is damaged I'll get them to remove it I think, depending on what's involved.

Turbo to intercooler hose. Clamp to the intercooler not fully tight.

- new alternator
- new fuel pump
- new radiator
- 4 x new Michelin tyres

Thanks guys. Someone approached me on a forum in the UK and I thought no harm!

The car now has a wideband o2 controller and closed loop knock control has also been set up using the factory knock sensors. There is still some wiring to tidy up so I haven't got it back yet. It's had a tune and is making another 50nm at the wheels, which should be pretty noticeable. Looking forward to taking it for a drive. All the work has been done by Dave at TuneTechnic.

The car is back from Tune Technic. Really happy with what Dave has managed to do. It's now fitted with an ALM wideband O2 sensor and 4 bar map sensor. Knock control has been hooked up using the factory knock sensors and tuned to correctly retard ignition in the event of any knock.  And a speed input has been configured which allows me to run gear boost trim as well as set up speed lockouts for the idle speed control. He's fettled the tune to eek out a few more KW, now running peak boost of 1.6bar or 23psi, which is about the most you can get out of it with the factory waste gate spring. Best of all though, I've now got a rock solid ECU platform that is performing great and has useful safety features enabled. Dave now has a state of the art Mainline dyno which has allowed him to get back into working on aftermarket ECU platforms. He also does factory ECU tuning if that's your thing.

Edit: I forgot to mention the best bit of all  :P, a little switch under the dash allows me to switch between a low boost map and a high boost map.

Copy that! I've set up 2nd low boost map that activates below 60 deg water temp which limits the boost to 0.8 bar. Should prevent me from getting me carried away when it's cold! So I've got a 0.8 bar warm up map, 1.4 bar 'factory' map and a 1.6 bar high boost map.

Wow  - very tastefully done

So with the Link more KW than standard ECU  ? ie 190KW atw what do you recon at the fly wheel ?

The factory ECU is very capable but it's getting harder to find people who can tune them. There are plenty of tuners in NZ who can tune a Link ECU. My car already had a Link when I bought it so I ran with that. Regarding your second question probably 240-250kw assuming 20-25% drive train losses. Chassis dynos aren't really an absolute measure though, but they are great for optimising tunes and doing before/after comparisons.

Confession. I removed the H&Rs last August. It's not exactly a stance king any more but it's got more compliance/suspension travel which is what I was after for family duties. I'd still like to get the KWs certed as they worked well while lowering the car but it's a modern classic now so not really worth while.
