boost problems.....I think.....

I have some issues with truck but I have been working crazy hours at work in the last couple of months so getting the work done has been impossible. Here are the problems.
1. my turbo vanes are sticking. going to pull it apart and clean it this weekend.
2. my truck needs a new ficm.
3. my truck has a cracked Y pipe I am pretty sure. going to order a new one.
4. my one intercooler boot keeps blowing off right off the turbo. I am going to do a CCV mod this weekend and order new boots.

The newest problem is. My turbo has always been laggy see problem 1. I can hear my turbo spool up when driving normally. From 0-20 MPH there is no problem. However when I try to speed up on the highway it takes me about 1/2 mile to get up to 60 MPH. I go from 0-20MPH no problem but anything over that its like my turbo is non-existent. I do not have a chip or any code readers or anything. My truck is pretty much stock. If anybody has any new suggestions please let me know.

Thank you.

I forgot some more info. Its a 2003 that was built in jan of that year. Before winter I did an Egr delete, new oil cooler, fuel filters, straight pipe exhaust, AFE cold air intake. If that helps at all.

depending how bad that y pipe is leaking it can cause your issue. I would do what you already plan on doing and then recheck it. Everything you are correcting can all add to low boost and/or low air flow.
