I am getting things done little by little over the next few weeks before I get a tune. I am wondering how much stuff to install before getting a tune. I have my cat back installed and just put my mbc on tonight and got it to the stock psi but I also have a 255 fp sitting here and have a down pipe, hfc, perrin intake system on the way. How much of this is safe to install before getting the tune done? The reason I ask is I would rather be able to put it on as it comes in rather than right before I get the tune done if possible just incase something comes up that may delay install. If I am thinking correctly the fuel pump with make it a little richer but will it compensate for the tbe and intake?

 

fuel pump will cause the car to run quite rich

no point in driving around with that installed if you don't have to

no matter what you do...don't rip on the car

 

im about to do the same, id wait till you have all the parts and install them all right before your tune.

 

how much boost do you plan to run and is a fuel pump a must with these bolt -ons for a tune? im kinda in the same situation...debating on getting a fuel pump??? dont mean to thread jack

 

this thread is over a year old. i wouldnt install a fuel pump until the tune
