Hey, who has upgraded they're fuel pump?

can anyone tell me why i would or wouldn't need to upgrade my fuel pump.

right now i have the turbonetics kit on the auto tc but i'll be doing a manual swap

will i need to tune right away with this fuel pump upgrade? would it be pumping too much fuel along with the big injectors?

I was looking into this and I am considering buying this right now. Should I just wait until I get tuned later on?

 

it provides more constant fuel pressure especially with bigger injectors and higher hp.. more than 550 inj its recommended. it will make your current map rich across the powerband so you should tune it after install

 

okay so it would be better to buy/install before my tune later on, i'm already uber rich in boost so it would suck to be even more rich.

 

You don't need a fuel pump. If you got one, you'll need a retune. I have no problems flowing enough fuel for 12psi on a 57trim T3/T4 w/550cc injectors.

 

basically our stock fuel pump is sufficient for a good amount of power and the only reason i would need a bigger fuel pump is for like 450whp+?

 

Basically, I've never seen mine go over 12 gallons per hour, and that Walboro flows 65GPH. No clue what the stock one peaks at.

 

okay i see i see, how are you able to keep track of the flowrate of your stock fuel pump? do you have a fuel pump pressure regulator?

 

Scangauge 2. It's quite handy for tuning, especially for tuning at idle and cruising.

 

aahhhh okay, and you do recommend this right? can you entail what a scangauge basically does?

 

Theres a thread on here with tons of info. It's well worth the money.

You can use it as a scan tool, works as a gauge for RPM, TPS, GPH, ignition timing, water temp, intake temp, closed/open loop, and a bunch of other things. Has a MPG thing to keep track of your current MPG, tank MPG, daily MPG, etc. Works as a trip computer.

365motorworks on these boards sells them for 155 I think, and Doc Iso sells a cubby panel for them, for that oh so clean install.

 

damn thanks dude! so basically its like a cobb accessport for our cars

did you do the install yourself?

 

Yes and no. The accessport is MUCH better because it's made specifically for tuning and can only be used on specific cars. It's more along the lines of a scan tool.

It's only one wire for the install. I have mine in the cubby. Just remove the center console, route the wire to the OBD2 port, zip tie the wire slack somewhere, plug in and it's done.

 

its just plug and play? wow if its that easy i'm buying it now lol

 

Yeah, it's worth it just to use as a scan tool, especially if you're boosted. Makes pulling codes a breeze.



Only shot I can find of it installed.

 

thanks carbonxe!

i just sent in my order for the scan gauge and i'll be buying the doc iso now

thanks again
