K20and2500HD

I order one for my 6.2L and got the free Throttle Controller. Drive-ability was vastly improved from idle to part throttle to wide open. So smooth and precise, then turned on the TC and wow is all I have to say over 30 positions to choose from, it took a while to figure the best one for me, haha, but I loved it! I was so happy at the results that I emailed Mike at Soler Performance about reworking the TB on my 2017 6.0L and he did..... It works even better on the 6.0L than the 6.2L as far as throttle response, I do not have the TC on the 6.0L but it runs so much better than before, I guess GM was starving them of air, who would have thought..... I do want to say thanks to Mike and Soler Performance great craftsmanship, fast turnaround, and great communication and knowledge. I do not regret this upgrade at all, it's subtle but well worth it!! Thanks Mike!!

when you gutted your cat did it cause any echoing sounds or turbulence with the larger opening of the cat? Just wondering, I would like to do this but not if it makes an echoing sound or sound tinny where the cat is....

Thanks, didn't want to waste the time and money if it wasn't going to work. I am just tired of waiting for Borla or corsa to come out with the exhaust for the 6.2L. I don't understand why GM put such a wimpy sounding exhaust on a 420 hp beast, but thats my opinion.......

i have a db muffler that I took off of my 2009 HD that I was thinking of having a muffler shop take off my factory exhaust and put this muffler on and run new pipe or pipes out the side or both sides. what do you guys think? Will the muffler for my 6.0L work for my 6.2L? (Will it drone?) I am providing a picture with my leveling kit and 295/55/20 Nitto's cause I havent yet haha. Tell me what you think?

My service 4wd light came on tonight didn't ever put it in 4 low but that is where it is stuck, no speedometer, not putting any miles on the truck, Just a good healthy whine from the transfer case that tells you that it is 4 low. Every light on the knob lights up but the yellow light that tells you what your in 4, 4, 4lo. Talk to a friend that works at the dealership tonight and he said its probably the actuator. The only problem is I hate driving 20-25 mph for 10 miles at 3k rpm to get there but the snow drifts are really bad so it shouldn't be that bad. I only have 13,400 miles on the clock so warranty should take care of everything though. By the way I unhooked the battery to try to reset it (always worked on my 04') but didn't work. also 4lo is slow, slow slow, but its supposed to be haha!
