You replaced the fuel pumps so that is likely not the issue. The chip concerns me. With the secondary delete you should have a specially coded chip that makes operation in that mode possible. It looks like you have the wrong chip. That, to my knowledge, is not even an LT5 chip. The standard chip should really be a BFXBG. I would not run the car that way. Damage due to a lean condition can result and is likely why it won't go over 4000rpm. Code 41 is a memcal (chip) error, so likely related. Get the right chip in there and start from there. I would call Mark Haibeck and purchase a correct chip.

The more I look at your photo of the chip, it looks like someone has modified it in some way and not in a good way. As I said, call Mark Haibeck,
