Question for experienced 20g guys

[TYTILIDIE]

I have a modded 20g on my truck and I am running the stock injectors. Has anyone run into not enough fueling with the stockers for the 20g? It seems that no matter what I do I cant get enough fuel to this thing and cant get my o2's back into the 900's. Any help is appreciated. BTW, my INJ DC has never been over 80%.

I stepped up to the "blue top" injectors (36lbs) with my 20g and could get plenty of fuel. They are a direct replacement for the stockers that generally don't require much (if any) recalibration to run.

Re: Question for experienced 20g guys

do you have a wide band. ive noticed that data master/ other scanners show high o2 reading and a wide band will show that its running ideal or rich.

Re: Question for experienced 20g guys

You should really get a wide band o2 set up, the stock o2 sensor is really slow & inaccurate for the most part, I would not trust it.
I do not have a full 20G turbo, it has a 12cm housing & I do not run out of fuel yet.
How is your 20G modified?
Bigger compressor wheel?

Yeha its supposed to ahve the biggest wheel that will fit in it I believe. I got it from Waller.

So I guess maybe I do have some kinda of fuel system problem. I just dont knwo what it could be cause Ive gone through everything. Oh well. I do ahve plans to get a wideband but not sure when I want to save for a nice one cause Ive been reading that the cheaper ones you have to constantly adjust. I trust my DM for the most part, i dont think its lieing to me when it says my o2's are low. I guess I could be wrong. Ive just starting to wonder lately if its just that the turbo is too much but I have a friend with a 20g who runs a stock chip with it and evetrythin and his truck runs just fine. o2's are even right where they should be.

Re: Question for experienced 20g guys

I thought you were saying in another post you could not get that much fuel pressure?

I did say that but I have updated since then and stated that I got FP to function normal but it seems to act strange when it gets real hot out. Ive had my FP gauge on for three days now and it seems to be doing great ever since I turned down the pressure. I plan on dropping the tank and replacing the whole assembly and using the coregated tubing as my line in the tank. Hopefully this will be a bullet proof set up. I think my main problems lay in the pump tro fuel line transition.

So what are guys with the 20g setups in TY's averaging in the 1/4 mile et's and hp?? I know it has a lot to do with supporting mods and tuning but just thought I would ask.
