can i run a gt500 fuel pump with out a tune for a while?

 

What's a while?

 

Why would you want to? Without a tune it's a useless upgrade to me.

 

When I first had mine installed I didn't have the tune updated right away and my car ran fine , of course I didn't get the full benefit from them until I did. Your sig doesn't show you mods , most people only get them if they're S/C'd and need more fuel ...

 

i have a paxton system at 487 rwhp and 430 rwt with a b.a.p.,60 inj.and a ba500 maf trying to go over 500 mark.need to know about the tune because my tuner is in a training and wont be home for a wihle

 

Good idea to add one with the sc but get a tune!

 

is it possible to have the gt500 system installed prior to installing the supercharger? im thinking of having a shop install the gt500 fuel system in my car and then just taking my car home to install a procharger myself.

 

Yes but if you can do the installation of the Procharger than you can do the GT500 fuel pumps. They come with instructions and they are VERY easy to install. I did mine on the dyno in about an hour and than got tuned.

 

^ thanks for the heads up... do u know of any walkthroughs?

 

I believe FRPP has the instructions on their website.
