Hey guys,
Just wondering if anyone can help me... I have drive an R33 GTSt that now has a GTS engine. It used to be a track car, so it has a big (loud) Bosch 040 fuel pump, as well as a big ass exhaust. The car has been using 15L/100kms, which is quite disgusting and worse than it used to do with 250+kw.
I'm going to stick a standard exhaust on this weekend to see if that makes a difference, but I'm also wondering if the fuel pump could be too high pressure and over supplying, and therefore wasting a lot of fuel. The guys at UltraTune suggested this might be the case, but I thought that the injectors would stop it from pumping too much fuel.
If anyone has any insights or advice, please let me know!
Thanks guys
