Ive got an 06 Puma with a 250 HPDI with the T1 also, I cant get over 73 with it for some reason, can only get 5700 RPMs. DOG out of the hole also. Ive got a Hyd plate too. for you guys running over 80, can you explain your set up please. I have had 3, 20 footers and this one is by far slower than the others . I am running EXTREMELY light also. Thanks,
