First, thank you to those who have answered my questions here lately.
Finally, I got everything I wanted on my 2021 HO 3500 DRW.
The tunes are perfect.
That's exactly what I was hoping for.
I was trying to get through the 200-mile relearn, but I unexpectedly had to haul my horse on a 200-mile round trip before finishing the relearn.
I switched to the tow tune, and all worked great.
Perfect powerband when towing.
All temps are now running cooler, and I never saw anything over 900 on EGT.
If any of you are on the fence about whether to get the trans tune.
DO IT.
My truck had 46k miles when I did trans-tune and weight loss, and I couldn't believe how much soot was being recirculated.
I'm happy to no longer worry about that.
This is the best thing you can do for your Cummins if you want it to last and run much better.
I had tunes from another tuner, but now I firmly believe in IGC.
The tunes are the real deal, and again.
Thank you to the fantastic community here, who are always ready to help fellow members.
