When I peg my Maf on my ls2 how do I tune for a dry shot nitrous? Would it be in the PE table? when the maf fails is that what it reverts to?

Right now I am hitting 1g/cyl on the motor and on the first stage of nitrous I am t 1.24g/cyl and 511.99 at 5400rpm and that is where the maf fails and it goes lean, IAT stays low but maf no longer reads the n2o? this is about an 70 shot and is the first of 2 stages. Obviously I need to iron this out before i even think about number 2.

The Maf is already Patched to 15000hz.

Could this be a nozzle placement issue? Or am I expecting to much out of the stock system? The dyno read 548 rwp only takin it to 5700 becasue of going lean.

any help would be appreciated
