OEM Throttle Control for Manual JLU?

[justprentice]

I hooked my JLU up to my HPTuners RTD module just for some baseline numbers before I look to tuning options, and found something interesting. I am only seeing 76% throttle allowance on a full throttle pull. I DO have the manual but just upgraded to the ACT performance kit.
Questions for techs :

1. Reckon they pulled throttle when they did the ECU update to control torque load for the exploding pressure plates?
2. Would a piggyback or throttle controller open up full allowance, or will the ECM override the controller output, and I just need to go on and unlock/ tune?

for anyone that is curious, she got a 8.37 to 60mph with a lazy foot and traction control & 2WD only. I'd imagine the worst 60ft you have ever seen on paper. lol

you need a tune which involves jailbreaking your PCM if you want to address this.

One more reason NOT to take my 2018 JLU Manual in for the recall.

So avoid the ,manual at all costs now?

I don't know but we could use reviews on the ACT clutch if you feel like writing one. (Regular or heavy flywheel?)

I think I could manage that once I’m back to my laptop.
