so i was wondering, i'm considering upgrading the injectors. the mountune injectors 1200cc seem to be the ones i am leaning towards. However, with previous cars i have needed to upgrade supporting parts of the fuel system like pump and fuel lines for this to be possible. Is this something i should consider doing? is it worth wile for the money to spend? is there a lot of proven dyno benefit of this? and mo importantly, are the stock ones worth upgrading i believe are around 800cc would the stockies be adequate for a cars goal of around 350-380 FWHP?

Thanks in advance! just trying to map out my modification road now

The problem is lack of fuel flow at lower rpm. The high pressure pump can't keep up with demand. Adding larger injectors will just make it worse. I'd save your money for an aux fuel kit of you choice and be done with it.

When Mountune came out with these I was a bit perplexed. It would make sense if they had a larger pump to go with them.

:whs: no point whatsoever to add higher flowing injectors without a HPFP upgrade. Get a aux fuel setup
