Actually they are 440cc. I knew they were around there
If you put them on a GTST you have to retune the computer if not it will run really rich and choke the car. It will be a pig them.

I don't really know if that is bad at that level for the injectors but in my view that would be perfect. If it was pushing into the mid 90's then there would be a problem but this has some give left still so you are not underusing them.
