Rich/Lean Condition Im having a problem with the drivers side of the motor running lean, I have a -10 feed line that comes in on the drivers side and I thought mabe the front crossover tube was not enough so I added another -6, made some pulls on the dyno and the same thing, drivers side runs lean, mabe im maxing out my fuel pump im running the A1000 aeromotive pump.....im gonna try there bigger A1004 eleminator pump and see if that helps, dont realy know what else to try
for those of you who dont know my car its making just over 700rwhp

Re: Rich/Lean Condition how much difference are we talking here in AF ratios on each side?
do you have a 2 port regulator after the rails, or a 3 port before the rails?
with the engine management system you are using can you offset the injector pulsewidth to individual injectors? you can do it on stock pcms with LT1 edit and on sequential FAST sytems... would be worth it to do some EGT testing on each cylinder and get all the cylinders equal on a setup like yours

Re: Rich/Lean Condition With a batch fire system, my guess would be pressure drop from one rail to the other and or fuel volume problem....best bet would be 10 an feed "Y" with a -8 to each rail then out of each rail -8 to a 2 inlet 1 return regulator.. They do make a variable injector controller for the gen6 to enable to control some additional cylinder fuel control ,but I think your prob is fuel feed/distribution from rail to rail related.
