I took Justin out in Betsy just after we finished at the WM Xmas meeting. Betsy did OK but I was showing J the TORQUE Android App. I have recently fitted a new MAP sensor (manifold air pressure), which I believe is what is read & shown on the app. However I only made 15psi - (1 bar) on 3 to 4 degree ambient, where on tests a month earlier with 10 degree ambient I was making about 21psi. So later this evening - I went out again & reproduced the same results.

Do you think there is a cold limit thing here? Is Betsy showing me up? Is the TORQUE app wildly inaccurate? Or do I just have a boost leak somewhere?

Hopefully find out from a seondary source as I am off to HLM tomorrow on a hunt for a heater matrix amongst other small maintenance issues.

Humph.
