So been a hugely long time since my last update - and part of that was no news, part of that was bad news & another part has been the pandemic....
But.... There is progress!
Turned out the turbo was in a bad state; and was overboosting with the vanes wide open - eventually managed to get it sorted out by sending it off, but we had to wait post lockdowns last year for various factors - moral of the story, even a reputable tuning company can get it wrong, and worth budgeting for getting to checked after a first run - if it doesn't behave instantly as expected.
The controller is now in, and it's had a few sessions on the dyno in the very very very early stages of mapping both it and the ecu.
Don't want to mention numbers at this stage as it's so early still - but the shape of the torque curve is lovely - almost flat in fact, but a little to the "right" than we were hoping for... but again it's still very early stages so not a concern at this time.
Fingers crossed I'll be able to give some more frequent updates now going forwards
