You and I are in the same boat. Hey it is what it is. No regrets.
OK installed the tune and finished the steering shock and took it for a drive. Ten miles to the expressway and I did notice a better throttle response. I could never respond to that phrase before. How can an 18,000 to22,000 LB land yacht
have an improved or better throttle response. Well now I understand.
When you depress the throttle you can feel the engines immediate response. Now I'm not talking about WOT
(that's wide open throttle
for all the non gear heads) I'm talking about a moderate depression of the throttle. If I choose to I can for the most part keep up with the cars normal acceleration from a red light. I usually don't do it (not in that big of a hurry) but i did try and could.
Got on the expressway and set the cruise at 65 MPH. All went well for a few miles then I hit an overpass. The tranny did down shift to maintain the 65. The RPM's went from about 2,000 to 2,500. It stayed at 2,500 until I got over the first OP. That was a good thing. On the next OP it had to shift down another gear and the RPM's went to 3,000. The best and most noticeable aspect was when it crested the hill it immediately down shifted to 2,500 and then down to 2,000. Under the stock tune it would have stayed around 3,000-3,500 RPM range for a much, much longer period of time. That was always the part that I hated.
I don't mind when the tranny gets into the 3,000 RPM situation but with the tune it shifts back down as soon as is reasonable and feasible. I went about 8 miles and was happy so instead of wasting any more fuel I headed to the barn.
We will be taking a longer trip next month but for now I'm happy with the TUNE. Without the constant down shifting into the 3,000 and then soon the 3,500 RPM situation is great.
I still use the TH mode for engine breaking. I don't know if 5-Star deals with that but I think I noticed an extra down shifting that occurred not once but three times as it down shifted to stop. It was nothing harsh or unwanted but it seemed there was more downshifting going on than before. There may have even been an extra down shift that happened as I got closer to stopping. Maybe it was my imagination.
I have been told that one can't recognize a 30 HP increase and that may be true. Maybe it was just the throttle response or a combination of both. I'm going out tonight on the local strip and look for some action!!
But I won't take the title with me.
I'm pleased with the tune.
Great job 5-Star
