i keep having this problem, everytime i press on the gas the car keep leaning out and have a hard time keeping normal and if i try to accelerate just normal keep leaning out. what could be wrong????
Fuel pump perhaps?
"You can only feed them semen for so long before their legs fall off."
but im running the stock pump and the msd inline, do u think i should change the pump?????
Yes, when ur boosted your SUPPOSED to change the fuel pump. Well, if you want any kind of power that is.
Grab an MSD in tank, Racetronix Intake, or a Blazer OEM pump.

racetronics for the win. that would be the way to go
How long have you been tuned, by who? If you have a booster pump you should be ok, but what is your fuel pressure? What is it leaning out to? When did this change?

i've been tune around 5months by HP Tuners, and it runs fine but as soon as i press on the gas and when it wants to boost it starts leaning out and after that if i let go of the gas it wants to settle but as son as i accelerate just enough to drive it,, the car leans out bad.
Has it done this since the tune was put in? I am betting your tune is off...

So let me get this straight... It started leaning out after installed the turbo? Did you ever re-tune it after the turbo was installed?

LOL! Hope you did!
If not I have seen alot of people boosting and running aftermarket fuel pump with stock fuel filter.
Make sure that your filter is clean, and that it can flow the amount of fuel required at WOT check out summits catal. for the specs and filter sizes

i was thinking about the filter and i bought a new one (stock size) do you know the part number??? or which one should be the correct one? i have 72lbs injectors, and the msd inline pump(external) . if changing the filter does not help im going to buy the walbro pump
umm octane?....you got the cheap stuff in there?
my supercharged eco runs liek crap w/ 87
You never answered my question....... Was the tune updated after you installed the turbo?

x2
Also why would you think of changing to another fuel pump? If you are already on a upgraded pump.

after working all weekend and changing fuel filter finally got it to work, the problem was that mi msd pump was connected with the stock fuel pump so the pump was not getting enough voltage. what i did was just connected direct with the alternator and a relay and ground from the chasis so now everytime i press the gas its running rich and better
well better because before it was running lean so i think this is good, now just need to re-tune again
oh and i use 93 octane fuel
after fixing my fuel pump on leaning problems i change stock my fuel pressure regulator for a adjustable fpr and that f%^# my fuel system again what would be the right fuel pressure for my 72lbs injectors????
Fuel Issues...REALLY Could use Some Advice
I believe stock pressure is 43.5 PSI at idle. Most after-market regulators come set from the factory around there, but not always. Also, if you switched from stock, you might have to re-tune after you install the boost-referenced regulator (and I assume yours is boost referenced). The line for the regulator should go to the manifold too, not anywhere upstream from the throttle body.
