Double Dark Side! Diesel & 8P
I read about a few instances where the mixture hadn't atomised enough before hitting the TB and caused issue with the TB. Welly's was one of them.
I have however just spotted this which is fitted to Wak's TT
This will inject the mixture after the TB but before the AIT sensor which is perfect. I might use just the pressure switch but inject after the TB to avoid any damage that might occur.
Tony do you use water/methanol or just water? Have you had the cooling benefits mapped in on your car?
