1999 Pontiac TransAm LS1 automatic Procharged. Issue is that it feels like I have no over drive. City driving an part throttle is great. Stays stoic and idels smooth. Only fault I am getting is the high idle P0507 or something like that. Anyways from a rolling start(5 to 10 MPH) it has no balls. From a 45 MPH roll I can floor it and it feels like I am at 15% throttle. Any help in the right direction would be awesome. Thanks in advance.

Transmission settings were way off. Not sure when or why I changed them, but I put them back to stock and shifts like it should. I will try to stiffen them up a bit today and work on my boost gauge in the VCM.
