Is it worth delaying my tune until the pump shows up? or is it not that big a deal? Does swapping out the fuel pump have an effect on the tune at all?
Thanks guys again sorry if it seems a bit of a noob question

Re-Tune for fuel pump?
by kennysti » Fri Aug 24, 2012 1:10 pm
Might be the wrong spot ot post or possibly a very silly question, I'm upgrading my fuel pump to a Deatschwerks 65c to go with my bigger turbo build. Basically I dont know if it will arrive before my car is due to be tuned again with the intake, turbo, TMIC and 3 port solenoid.

I don't think it should make a difference since the flow into the engine is controlled my the injectors but take my opinion with a grain of salt.

There is a good chance the pump won't flow well at idle and cruise unless you run new wiring and a relay from the battery.
Aftermarket pumps require over twice the current so you generally need to upgrade the power wires to the pump, also they don't seem to like the factory low voltage at cruise/idle.
Do you have a wideband o2?

no need for remap or extra wiring for DW65c i fitted one about 2 months ago and no issues with it, it did help lower injector duty cycle by about 5% though

This is news to me. Anyone else of similar opinion?

That's my plan since my car is at 170K... Did you change the filter part as well ?

Bugger thought it was a bargain at $159 + postage. The carmods website says on special..

Great excuse to visit Tuspeed 
So if my 170K stock pump fails, will my car EXPLODE?
Or do I have better things to worry about?
