ok i'll try to tune the car first ...
after that ... i can install the Fuel pump ??

 

install the pump and then tune, just don't install it and drive around too much.

It's a good idea to install all parts before tune

 

No, you do the fuel pump in preparation for the tune, but you don't want to install the fuel pump and just drive around without a tune for long. Get the tune immediately after the fuel pump install.

 

ECHOOOOOOOOOOOOOOO!!!

 

alright .. these stuff what i have got now .. but not installed ...
Injen intake with upper IC pipe, Lower IC pipe,abd MBC
so can i install the MBC without the fuel pump ?
and what if i installed the fuel pump and driven it alot ..

sorry cuz of the questions ..
"i am learnin" and because we dont have any evos here .. so im clueless and dont have anyone for advice ..

 

Yes, you can install the MBC and those other mods without the fuel pump. You don't need the fuel pump until you start running big boost on race gas or alky. It is recommended you get one before a flash just so that the flash tune can give you optimum safe power and so that you don't have to get retuned in the case of adding a fuel pump later.

Driving around with the fuel pump while untuned won't hurt anything, but it will just suck ***, since you are only making a bad problem worse. The factory tune is extremely rich, as I explained before, and a fuel pump just makes it MORE rich, which means less power.
