Default Walbro 255 not enough, What next?

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!

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?
