Tuned the truck after a cam swap. On take off the truck is sluggish until about 3,000 RPMs then it will pull hard. Then at around 55-65 mph the truck surges and jerks almost like wire is loose. The transmission is not shifting hard when it is WOT, but when you are cruising or riding through a parking lot it shifts extremely hard. Checked the computer forDTCs and it shows none. Any help is appreciated. Thanks.
The info on the cam:
