Post your tune file so we can help out.
ahhhhhhh. I will need to get that. Its on the lap top and I am at work. this is new to me and trying to learn as fast as I can. I do understand that when tuning you can make mistakes and can create issues. I was just tweaking things. Did make improvements but.........with the VVT unhooked it just does not have the power.
VVT cams parked does not mean cams are straight up...one is fully retarded (exhaust) while intake is fully advanced. Runs very sluggish.
