So I installed my new gryphon cs a couple weeks ago. I finally got my gps out yesterday since we're going to Colorado and I noticed my tire size was quite a ways off. So I re programmed it a few times until I got it just right. But once I programmed it the last time I noticed I had some problems. I always keep my load meter up and it used to get up to 75 and pull real nice and then downshift. Now the load only goes up to around 50 and to speed up you have to essentially keep pushing the pedal down, load remains at 50 and no power goes down, then once you have it almost to the floor it finally downshifts and I'm on my way. I did redo the program to try and "fix" the issue but to no avail. What gives? It's like it won't put out any power until it downshifts which requires flooring it to put it simple. I really felt it and the load meter confirmed it. Any help is appreciated so I can get it rolling right before the trip back through the mountains!

Brent, I responded to this post in the PHP forum.

It sounds like you might want to try adjusting the downshift and torque converter unlock points.

So would only want to mess with the unlock points? They go on a mph basis and I didn't really understand them. Why would they only change so drastically after re programming my truck the third time? And why would the load number no longer go higher than around 50?

 

What doesn't make sense to me is why it would change from one tune to the next? It's really like my pedal is almost unresponsive until almost floored, and response time is horrible. At least a one to two second delay from pushing it down to it responding. All of this started after the third tune fine tuning my tire size...
