4hi is useless, especially from a dead stop and on some muck. Jk is unlike other rigs, how is your TC disabled? Steering dance or custom switch? Funny thing about jk, you rely more on driver skill than sheer power .....I don't think you any engine problems.....

 

I used the code to full disable the tc, 70 or so tries at least haha. Most of my wheeling has been in a 78 bronco with a 460, it has been 2 years of re-learning with a vehicle that reacts completely differently. I will just get used to the power issues unil i can get a good diesel. Thanks for the the useul information guys
