VGT TURBO FAILING???
The last month or so I've been noticing my truck not being as responsive as it use to be this truck use to brake the tires loose through 3rd gear on my 250 tune and peg the boost gauge in the dash at over 40psi monitor read 45psi when going into lockup This truck has spartan tuning dpf deleted obviously and egr delete 4inch straight pipe exhaust and AFE cold air and now I cannot get it to build more than 30psi of boost on my 250 tune??? What the bells goin on I just put new NDash on my dads 6.4 and he spanked my truck on his 210 tune I was on my 250 tune now my tuning is the update with early and late lock, could one or both turbos be going south? I checked for boost leaks it's sealed tight

Also both mine and my dads are 2010 6.4 psd both 3:55 gears only difference is his is NDash mines dashdaqXL his has the newest update and his is s&b cold air mines afe and his is flo-pro exhaust mines afe also his is louder than mine that doesn't make any sense there both 4 inch straight pipe and his is a hell of a lot faster but his feels like what mine use to feel like?? Some one have any idea where to go? Also at 80mph cruz control on I'm only at 6psi of boost I don't remember what it use to be
