Quick update on the work so far, the new turbo has been installed and now the mapping is being carried out. The spring on the modified wastegate actuator was too stiff and did not work well with the initial tests using the tuning box I had so this was temporarily replaced with the standard one.
After a day spent mapping and tweaking the uprated actuator is going back on again. The car is currently only running an ITG panel filter as the ITG intake production model is still being finalised and tested on the rolling road for proven gains before it is sold.
The car has been RR'd on a hub dyno and is currently giving 180bhp and 320 nm of torque, with the continued mapping tweaking and addition of the actuator and intake I've been told to expect an additional 25 or so bhp, boosting and holding longer at 1.4 bar and reaching 1.5 bar on overboost. And all this form a car weighing just over 1000kg and with a 1.4 engine.
