OK, I figured out, finally why the DYNO tune will kill some of the trucks.
What I need is one or two or more guys that have a truck capable of 4K and have a little spare time, day or night. Basically what I want to do is send you some custom tunes via email while I wait on your feedback. We can go back and forth until we get a couple of these quirks out of the dyno tune and big injectors. Stuff like holding high rpms on PL10 etc.
To start with, I just want to know, does it go to 4K. Second, I want to know can you hold a high RPM and light throttle, or within reason.
I can do this pretty much anytime, any day, any hour. My poor little old trucks just cannot take this anymore and I am getting a little tired of messing with it on a whim. If I had a truck that would handle it, it would be done. I bet it takes less than an hour or so to get it where we need to get it if I can tune and get positive feedback.
Let me know if you are interested.
