yea i was kinda shooting in the dark with the egr. i need to test my ficm i have had it at the shop 2 times and told them mechanics to check it and both time they told me no its fine, kinda thought i pay them to do what i say but apparently not. so i am going to get a voltmeter and do it myself, since the knew injector it runs awesome i love my turbo. it still seems to have some issues with it, it never ends haha. so the knew problems on the go:

somtimes when driving going about 80km when it shifts the rpms stick at around 1500 and when i push down it just sounds like it sticks and whistles. it will only unstick if i floor it and it revs like crazy and shifts or if i let off the pedal and let the rpms go down ghen back on the gas.
also somtimes when going down a hill and i apply the brakes the front end shakes, i have looked it up and it seems like i might have a rust problem. i just got new tires and iam going to look into that when i switch them over.
