Yeah i'm lost seb

 

thats far tooo lean ... your bound to melt something and im just having a hard time seeing how you makin power [&:]
a safe range for turbo cars is between 13-11.5 if your in the low 11's you overfueling for an inneficient IC or a maxed out turbo that works past its efficiency range and instead of compressing the air also overheats it!

been down that road an it just not worth it. if its in the case of the turbo ... time to upgrade to something a bit more efficient

 

I just realized he meant boost... whoops lol

 

for 660 cc injectors should i go with a 255lph fuel pump or the 190lph one cuz they both cost the same?

 

The 190 is fine. The only problem with the 255 is that you need an aftermarket fuel pressure regulator. So, it does end up being a little more.
