Torque wars continue in the diesels

For those of you that are getting those numbers (ShinerBock), where is it most noticeable? If you were to turn your tune off while pulling your RV, where would you notice it first?

I cannot turn my tune off while driving, but I can switch between power levels on the fly. It is tuned via EFILive with a CSP4 switch. It is a 4 position switch the goes from 390 rwhp/802 rwtq in position 1, 450 rwhp/948 rwtq in position 2, 470 rwhp/1020 rwtq in position 3, and 515 rwhp/1105 rwtq in position 4. If I go wide open throttle in position one and switch to two or three while still at wide open throttle, then you will feel a surge in power as you switch to each position.

I generally stay in position two empty or when towing light and in one when I am towing heavy. I don't really want to go higher than that on the stock trans and torque converter.

The torque converter on the 68RFE and Aisin is too inefficient compared to Ford and GM's at putting the power to the ground unlocked in my opinion and needs a lower stall speed. This is one reason why it takes off so slow because it just spins wasting engine power and doesn't really take off until locked. A triple disc TC with a lower stall speed is a night and day difference from stock even without adding power.

It's not the torque converters, it's the puter limiting torque in lower gears to save parts. All manufacturers do this.
