If you have an intake gasket leaking it will be running lean when tuned for your 44lb injectors in open loop. Probably cause your high map as well.

What brand of injectors? Did you use a lot of sealant on the rear and front of the manifold. I saw where one guy used to little and had to redo it and he still didn't use enough. It took him four tries to get it right. You might be able to feel back there and see if you have any oil coming out. The front is mostly by sight.
