With the correct ECU program the 740cc injectors can idle, use the same amount of fuel and run the same as the stock size injectors. The amount of boost you would run has no effect on how the injector works at low speed.
You could even run the 740cc injectors in a NA with zero issues.The DW injectors are a big gamble though......
I have received many calls from customers that have purchased DW injectors from other dealers (as we will not sell them) and have had many reports of poor low speed and injector failure with DW injectors.
DW modifies smaller old injectors to make the 740cc and it reminds me of the RC injectors that were done the same way 10 years ago that started out as all the rage and later everyone found out it was a poor idea and failure after failure was reported and it became a option no one used after some time.
:First of all I'd like to thank everyone who contributed their valuable time and share their knowledge on this site. I am truly grateful for all the helpful info that make my experience of owning a Z so much better.
:I am at a stage that I have to replace all the injectors and I plan to install Deatschwerk 740cc and Apexi single intake and have the ECU reprogrammed for the bigger injectors. This is where my budget ends and it will be a while before I can afford a decent boost controller. My question are..
:1/.Can I run 740cc on stock low boost for a long period of time, months, years?
:2/.Will 740cc and reprogrammed ECU make my otherwise stock setup run too rich?
:3/.Can I use boost jets on the 740cc ECU program?
:4/.Any advise and suggestions on the above?
:Thanks in advance for your input!
