Default Kc S300 63/68 or 63/73

Running a 2002 F250 as a dedicated tow rig, just exploded the billet wheel in my 38r. Was never really completely satisfied with that Turbo, although it was a significant upgrade over stock. So what are yawls opinionWhy or why wouldn't you get the bigger or smaller turbine wheel. Truck has stock injectors, 4" downpipe, bellowed up pipes, and ******d pedestal. Also running DP tunes

FWIW, with stock injectors I would run the smaller turbine housing for quick spool up.

Yeah that is my plan, That is also what KC recommended, They also recommended the 68 whee, especially for a tow rig. The largest injector I would ever put on this truck would be the smalle hybrid, 205/30s and that's just because it's easier on the oil system I can detune to whatever's needed

Well the 205/30s change everything. You need to decide if you are staying stock or going with 205/30. Stock and 160/0s would be great on the 68 turbine wheel, but you would want the 73 with anything bigger I would think.
