So we're tossing a Kong ported Edelbrock 2650 on a cammed LT4 Z06. The car was tuned by someone else originally and we figured we would start by just updating what we needed. Dialed it in on the street without any real issues. Car seems to drive fine and idle ok but as soon as we floor it on the dyno it just sputters and makes not power. The bank one o2 sensor kind of goes crazy while it sputters and then drops very low. Any ideas what would cause this? We smoke tested the car and it doesn't seem to have a vacuum leak or anything.
