PCM code??? and tunes???

[SubVet]

Ok, I'm about ready to order my chip, (6 position)

I think the PCM code is 2KWM or 2KMW it was very hard to read. I also saw a VCEE on the sticker

I don't tow often, but when I do it is around 8k, there could be occasions that I tow 10 or 11K, which tow setting should I get? Since I am planning only to get 1 tow setting.

This is what I am thinking, any thoughts? I mostly use the truck for fun, I like smoke, but want to preserve my transmission as long as possible and want the fuel economy.

1. Stock
2. High Idle - 1,100rpm
3. 80hp Daily Driver (how hard is this on my tranny?)
4. 65hp Moderate Tow ????
5. 100hp Performance
6. 140hp Extreme

My truck is a 99 (jan. 6 1999 build date on the motor) f250, 4" exhaust, 89k miles, 4x4, 4r100, 4 exhaust, Airaid intake, AIH delete, HPX, stock injectors, stock turbo, gauges (egt, trans, boost)

Thanks,
Jim
