Just installed both intake spacers and PCM from mace (stock exhaust) . Amazing to drive... Gear changes are twice as fast (auto). No longer bogs down. shes a completely different car to drive. the shift from 1st to 2nd gear is unbelievable it just keeps pulling. Also when revved in neutral there is a little cackle from the exhaust. more prominent with a quick stab to 2700rpm like a very deep popping noise, not loud you can just hear it with the windows down.
In the engineer mode Fans turns on @ 95 degrees.
on stock tune is used 1.9 litres per hour (instant usage readout) @ idle. Its now down to 1.54 with the mace pcm.
Fuel economy has been much better since the install when driving normally.
The Throttle response is magical massive improvement.
On the stock tune @ full throttle it was using 37 litres per hour in first gear. Now when you plant it uses 60 litres per hour. It accelerates way quicker compared to the stock tune. I cant speak highly enough of it. I felt like I was dreaming after the first drive.
Would recommend to anyone with an Ecotec. Should of done this years ago.
