Been offered some for a hybrid build, does anybody have any thoughts or experience of these? Don't want to turn up for mapping and be told to go away lol
Personally I would stick to Bosch/Genesis 550 EV14's... these are a known commodity among the decent tuners and work exceptionally well... I even run these on my BT setup with a 4bar FPR...
You got any specs on them? I can't seem to find any of the usual dealers listing 550cc siemens... if a tuner can't find the data for these then your performance and fuel economy could be effected...
