pro cal tune

I want to add the Ford pro cal tuner but was wondering if any can answer a couple questions ? I did the muffler delete through flow-master and added a K&N air filter. There’s definitely a lag in throttle response and sometimes I feel it cut out. Like it’s an air to fuel ratio mix up. Will this...

Brand new in The box unopened ford pro cal tool and tune for the raptor. If you have an RTR front grill and want to exchange let me know.
