Double Dark Side! Diesel & 8P
Just seen this thread.
Firstly, my injectors were (according to the VCDS logs) running at around 130% of the capacity which basically means they were wide open on boost and struggling at 3 bar. The car was only running a dyno'd 260bhp on a revo stage 2 map!!!
The main bits of hardware that tipped the injectors over the edge wet the XS exhaust manifold and the AEB large port head I'd fitted. At this stage I already had a brand spanking new OE fuel pump and my WMI wasn't working correctly.
I ran a 4 bar FPR to tie me over till the custom map was done on Bosch 550 injectors. As said above there's loads of mapping info for 550s so seems mad to try a Chinese brand.
Oh and just for the record slowcoach, 300bhp is possible without a hybrid turbo
