After installing the 60 psi injectors and GT2-3, can't seem to richen it up. Reading 10.8's at 1psi but once I go w/o throttle it leans out to 13's. What should I do to help this pump or what other pump can I go with that wont cost me a bunch.
I'm going to try 2 walbro's in-line and in-tank to see if they work better together. Pls HELP!

 

Boostapump?

 

Link?

 

Not sure....i know alot of guys with the maggies run em on the stock pumps to get more fuel from em though.

 

huh?
are you sure the problem isn't in the tune?

 

Magnavolt, get it from your Magnuson dealer...

 

Thats what i was thinking of!!!

 

I think there is definately something wrong here.. I dont know how you could be running out of fuel and going that lean. I would check the tune and fuel system before adding anything else. The charger should also be making a ton more than 4 psi.

What pulley are you running?

Have you checked your fuel pressure under boost?

 

Did you tune your pe table correct. I have heard people having a hard time getting the 60lb injectors set up correct. Check your tune again. I was running 8lb and a 216/224 with 42lb injectors just fine, and a walbro 255lph inline pump.

 

I'll re-check with my tuner see if we can figure something out. The 42# injectors were around 102DC @ 6000 rpm with only 4 psi. That's why I decided to go with bigger injectors with the cam swap. So tuning should fix this without using the boost a pump?
