i ahd mine tuned for 70-80 removed during regular and 100% gone in tow haul.

 

I thought in on eof the conversations that I had with Allen that he said he could adjust engine stuff too with the tow/haul button oh well I guess I was dreaming.

Zippy I have killed a transmission by taking all tm out. When I got my truck tuned by Allen I got him to take all tm out. Before the tune the transmission was fine after the tune the clutch packs blew. Allen told me to be easy on it till I got a shift kit and servos in it but I couldnt keep my foot out of it and about 20 miles after the tune boom my tranny was toast.
