Default Dyno Results - Help!

ok, so a little backround on my car:

2000 z28 - headers, y-pipe, cut-out, 4000 fuddle converter, 4.10 gears, ls6 intake, custom cam - .573 lift 228 duration 112 lsa, 42 lb green top svo injectors, 125 shot dry.

Here's my graph. The converter was not locked, so i understand why the numbers may be a bit low. What do you guys think?

Also, maybe this belongs in the nitrous section, but what would cause the MAF to not read the nitrous going through it? Basically, the computer is not telling the injectors to add fuel so it leans out. We tried turning the nozzle backwards, it helped a little bit and yielded the same power, but it's still leaning out bad.

Was the cam degreed when it was installed? It looks like you are running out of air right away. Unless there is a problem with the exhaust.

mmhm, A locked converted #1 would be a HUGE benefit.

Also, if you havent already, take it to a guy who knows how to tune and understand n2o kits, Assuming you have a dry kit.

the cam was aligned dot to dot it had 4 degrees ground into it.

hopefully that makes sense.

You might be blasting through that converter. Was it specced for nitrous?
