Hello Eric. I had your version one chip for almost 12 years and thank you for a great product. I ended up having some issues with my injectors so i decided to upgrade to 60lb injectors and go with the new TT chip. My truck is stock turbo and motor except for the upgraded fuel pump, ractronix hot wire kit, forge wastegate, accufab fuel regulator set at 42lb with vacuum off, and your 60lb injectors and chip. Everything is installed and truck idles and runs fine however I cant get more than 5 pounds of boost. I verified that i have no boost leak. I even went up on parameter 6 max boost target from 113 to 120 and also adjusted my wastegate rod I only get 5psi and nothing more. I'm using Tunerpro for logging. Attached is my last three runs. I appreciate all the help you can offer.

Everything looks fine in the logs. Wastegate duty cycle is 70% which is normal. So there must be something mechanical wrong. I would check the wastegate hose plumbing and wastegate function.

Hey Eric. I went back through the truck from vac lines and all turbo clamps and one of clamp nuts just kept turning but not getting tight. Changed it and bang drives and boosts great. Thanks for your help.
