How many of you guys are running 60lb injectors on a returnless fuel system? I know there are quite a few doing so on a return system but... Off the top of my head Trever1t is the only one I can think of on a Returnless. Just wondering how they were as far as tuning due to the Returnless systems high idle pressure. So whats your opinion on them?

 

Well I don't tune so I can't really answer but I can tell you my engine idles fine, maybe slighty rougher cold (?) but not really any rougher than it did stock.

 

Cool, (fixed my misspell of your SN) So it maintains a normal Idle AFR, are you MAF or SD?

 

Both, MAF enabled to a point and then SD (custom OS). Yeah, A/F at idle is 14.7:1

 

So anyone else???

 

i had them when i was returnless and it idles great , as good as stock . i eventually got to the limit sof a one pump / bap system so i switched to return.

 

Did they require any special tuning? Obviously IFR, how about Min pulse, default pulse, Voltage offset etc. Just trying to get a idea what to expect before they show up.

 

My truck idles real good. Thanks to Allen Nelson.
