So I have an f150 with an Edelbrock 2650 and smaller pulley. I have gone over the tune in every possible way. And I cant get over the part throttle surge as I approach boost. I moved the torque model up and down in the area of error and nothing would help. I am now using the whipple torque model as I have messed with the oe one farther than I can tell and the Edelbrock tune just lowered the thresholds so it wouldn't report any ipc. I have attached the Edelbrock tune my current tune and the log.
