Well we never did do a dyno pull with the stock throttle body, but tuner said he thinks I picked up a good 30+rwhp from the CJ throttle body since he usually sees 460rwhp on the 3.5 pulley.
497rwhp and 469rwtrq on the 3.375 pulley
Did not try the 3.25 pulley. tuner thought the stock fuel system would not keep up and didnt want to risk it.

Runs like stock. They agreed these new Ford ECU's are a nightmare to tune, but they have definitely got the Raptors singing.
Truck is a beast. Deavers keep the rear end planted and it will smoke the back tires with no wheel hop.

Red line is with 3.5 pulley. Blue line is 3.375 pulley. Picked up a little less than 1psi, no real top end gain, but picked up a good 15-20hp across the entire power band.
