If I would push the pedal just right it would go into 4th if I was lucky, but buy then I was running very slow. I emailed 5 star about this and they sent me a new tune so it will shift into 4th easier. I wont be able to try it for a time we just got 8" of snow and no trips planned. Have you noticed this?
I installed the 87 daily-tow tune. 5 star is a great company!
I had the opposite issue on my 37DT on a trip to Gulf Shores late December. I had an Outlaw that I had first tried Mikes tune and was really happy. I installed the new one for my trip south but was towing a trailer. What I found was that all too often while in cruise control it would down shift into third and not hold that long enough to allow the V-10 to develop the power to hold the speed sot it would down shift and the RPM would jump upwards to 5k. I wrote to him while I was down there and he sent me a revision. I installed it for the return trip and was really happy once again.. Mike does run a great company and couldn't have been more responsive.
Best of luck with the new coach!
