Thniking about trying ******** myself. I went with tyrant and it’s very Smokey took me 3 months to get a revision and still Smokey a lot less but not impressed at all
I’m having the same issue on my 6.4 single turbo it was fine before. The new tunes but no limit is helping me out with everything their customer service is definitely top notch
over 1k miles so far on the rebuild and I can say I am far from happy with the tune waaaayyyyy too smokey partial throttle is very smokey doesn't clean up on full throttle doesn't downshift accordingly turbo loses boost in between shifts I tried calling no limit to see if they can confirm that...
Ended up going with tyrant the truck has a no power tune for “break in” period So I can’t comment on thhhe tunes yet but hopefully the street and tow tune drives better than the no power tune that’s in there now
I have a mpd s369 kit on my truck just waiting for the new tunes to really get a feel for the truck. Drove it in the old vgt on tune and it was a little laggy not bad but still there hoping the new tunes will fix all of that
