hi,

just want to know if i have to upgrade the fuel pump with an ultimate-racing kit? the kit doesn't come with a fuel pump but have 600cc injectors in it.

just to be sure

thanks

 

u should

 

Yes you need to

 

ok, but my a/f ratio gauge doesn't indicate that i am lean....always stay in rich part of the gauge even at 8psi...

why i should have a fuel pump if the OEM is ok??

 

If you're reading A/F ratio off the O2 sensor you may not be getting the whole picture. The stock O2 sensors bottom out (they're only designed to read a certain voltage range). You need wideband to truely know your A/F ratio picture.

 

Bump OP...

I'm in the same boat... any comments?

The way you should look at it with FI is.. The more prepared the better. You may not NEED the extra flow of fuel from the pump at your current boost level, but why strain the oem pump to where it could cause failure. Might as well upgrade it to avoid a pesky problem that you will have to troubleshoot down the road..

 

100 dollars and a few hours to pull the tray and you have a bulletproof fuel system. I don't see why you wouldn't do it...

 

Just what I wanted to Hear..now I just have to find which one I should use.... Thanks guys.. ^^^^
