Is there any option? Can a person install a simple cancel od switch in line between pcm and tranny?

Truck shifts much better with the H&S, but according to their site, there is still no cancel OD option that I have seen.

If not, I am going to drop my gears considerably.

Innovative has a delay loc tune, for me it holds o/d off till 60. Mike @ kem also made a tune where it uses the tow/haul to hold o/d off for a bit. I don't think anyone has a o/d cancel as far as tuning. Best bet is to change gears

Sh*t , I meant to say that mike's tuning does cancel the o/d. I have yet to try his tuning but I am going to soon hopefully, erics just doesn't hold it off as long as I would like but its not that bad

Yes, KEM built a 150hp and 345hp tune that allowed me to lockout O/D when we were first testing the single turbocharger setup.

What gears do you have where OD won't be beneficial when towing heavy?

2000 rpm at 80 mph. Pulls great at that speed as far as being in the torque (powerband) for towing. Problem is, that is too fast for most of I-77 and Ohio, Illinios, Indiana when towing. I would prefer my OD to be at 2500 @ 75mph, and be able to lock out OD and run direct 2500 @ 65 or so.

I can not bring myself to run 80 between Charleston and Beckley on 77.

I have Matt at Gearheads hot street tune with od locked out till 85mph when in tow/haul. With 55mph speed limits, I struggled with the same thing. I would talk to him.
