ive got my fuel pump and injectors ready to put on my car but need to save up for the tune, ive got full exhaust up pipe, and front mount should i wait to put these parts on for the tune/ how will my car run with these on w/o the tune

 

It will run like crap dude. Just wait a bit and do it the right way. I know how it is when u have all the parts ready to go and u wanna put it on and go, but the reality is that if u don't do it the right way then ur risking it. Ur car will run and respond much better with a tune then without one... I hope that helps. Good luck and go make some power...
