There may be an easier way though to get totally back to the "virgin" custom tune - just program it in and completely bypass the Custom Options step. Or, if you want to have a "Previous Settings" file that is mostly "virgin", open the Custom Options menu but DO NOT "Load Previous Settings". If I've got this right, you are now in the process of creating a NEW "Previous Settings" file, but most of the settings are what Bill wrote for you. There are two exceptions though - Tire Size (TS) and Gear Ratio (GR). One or both of those values will now likely be wrong and you'll have to manually set them. Check both and adjust as necessary. Then, scroll to "Done" and let it program. The new Previous Settings file will hold Bill's values and your TS and GR.

As I said though, I don't know if the RPM drop during braking is normal or not, since I don't recall ever looking at it. I don't think I get that big a drop, but I cannot be sure.

And, I'd give Bill's settings a try before trying to "customize" them. After all, it's what you paid him for. Also, if you don't like something in them, it's probably best to discuss that with Bill, so he can fix the root cause, which is different than you putting a "band aid" on it with "Custom Options".

That interesting to know. I looked at my settings earlier while I was out, I see Bill has it set 1-2 shift = 5100, 2-3 shift is also 5100, 3-4 shift is 4600, and rev limiter is 5600. I noticed that my avg econ was hanging in the 17 - 22 area, so i calculated some miles and compared my rpm and speed and realized that my tire circumfrence was wrong. It was 2340 something i think, and with the canned tune it was 2550, I did the math in the manual and came up with,, 255 x 70 x 0.02 ( 357 ) 17 x 25.4 ( 431.8 ) both together 788.8, and x that by the 3.1415 and got 2478.0, going to re-program that in the morning.

I'll definitely be testing out his settings. I was just wondering if there was any improvements I should make prior, but since its my truck and I have my driving style, I suppose I am the only one who can answer than question lol.
