Well the weather was a little cooler (80*) last night so I went for a little tuning session. With the new cam I am seeing 95% IDC, but the AFR is holding to what I am commanding 12.5ish at 6200, it varies slightly +or- .2, on various logs... Since the weather was better I was finally able to get into the higher Cylinder Air Mass values .68-.72, that is when my IDC hit 95%, so considering my options I am either thinking of some injectors or a intake Walbro.... Any suggestions/opinions?

 

What's your fuel pressure?

 

Hmmm, I dunno, I have an 04" with the returnless stuff I think... Do I need to check that first before making a decision?

 

Injectors.... Your fuel pump should be able to keep up with your setup fine, unless its going out. If you are running stock injectors then that IDC seems about right for your mods. Personally I would do both just to feel warm and fuzzy.

 

Get yourself a set of 8.1L injectors. I think they are ~31lb injectors. Making more fuel pressure with the intake wont do it. Your stock injectors are just maxed out. But if you want to do it right i would do both the injectors and fuel pump.

 

I believe the pump is fine, the truck only had 40k on it, i have never had a problem holding whatever AFR i command, but a walbro is only like $100, cheap insurance if you ask me... I like being warm and fuzzy , so I believe next up will be injectors and pump...

 

I hate doing things twice so I will just get both, it will probably be a month or so, but getting the airmass I did yesterday probably won't happen again for a couple of months, so I don't think it will be a problem again until the weather cools off....

Thanks for the advice guys!

 

 

 

You beat me to it
