Installed new MTW Hybrid, but I think I have a boost leak?
First off, this is in no way a knock/complaint about the turbo itself. I'm very excited to have gotten one and gotten it installed, but I'm pretty sure I have a boost leak somewhere that's not allowing it to perform properly.
I had my new Hybrid installed by my local shop on Saturday, along with new Riff Raff intercooler boots, updated turbo lines, blue spring, and banjo bolts. I had forgotten my SCT at home so I wasn't able to load a tune for that specific turbo until I got home - it was about a 30 min drive so I wasn't worried too much about numbers.
So I finally got a tune loaded on there written specifically for the turbo and hopped in and tried it out. I start getting on the highway, not stomping on it, and look at my CTS and see that my EGTs are at almost 1100 and I only have 11 psi of boost so I back off. While cruising down the highway on relatively flat ground at about 65 my EGTs were between 750-900 and my boost stayed around 2. The tuner thought the tune might be corrupted so I get a new one - same problem. So I load up a tune written by someone else for my set up and get the same things - over 1100 EGTs and no more than 9 psi boost before I let up and it cruises at 7-800 degrees with 2-3 psi of boost.
From what I've looked up this is a leaky/cracked CAC boot I think? I'm hoping that its just something isn't sealed since the boots are brand new.
Anyone have any other ideas?
PS, sorry for the wall of text.
