Re-Tune for fuel pump?

Visited Tuspeed today, bought DW65c, will pick it up next week and self install.

Adam is awesome, listened to my musings, and gave me great feedback and advice!
The shop is chockers full of goodies including some very tasty Lib bits, including Process West, Whiteline and AVO to name a few.
Nearly lost it over the 17 x 7 PROVA by Enkei rims... last set!

Self installed the dw65c kit from Tuspeed ($155ish) today plus a new in-bucket filter/pump-holder thing from Makin & Luby($90ish).
Took some pics for a DIY post: very glad I did this as the amount of crap in the various filters/buckets was amazing!!!
I love mods that can't be seen, heard or felt lol.
Mad props to Adam, Ashley, JDC, NASIOC bros. and this forum for the parts, advice and encouragement!

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?

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

The DW pumps are plug and play. The only suggestion I would make would be to watch the fuel trims with added boost to make sure the fuel pressure is accurate for delivery. If needed, an adjustable FPR is an easy install to correct pressure.

Ill be logging with a Tactrix later this week.
Subjectively, and with basic ECUdatascan logging, the Lib seems to be running great post pump upgrade to DW65c.
Fuel pump duty cycle goes from 33 to 66 to 100% at wot as reported by the ecuds.
