Stock 87 tow vs Custom 87 tow

[CredURDead]

I am just sending it in to be converted for the first time and just not sure what to put under the order form. Corey emailed me and told me I could add more tunes if I needed later, but there are three slots which say stock-tranny, stock-tow, and stock-performance, I am wondering if I should leave them that way and send it in.

I know I can purchase custom 87-performance and custom 87 tow later, which is what I want. But if I should indeed get them now, what do I do with the third slot. I guess I am just lost on what to do. I just started to mod out my truck, havent done anything with intake or exhaust, probably won't either due to my fear of rusting out an exhaust in 5 years(MN salt in the winters), and fear of leaning out the fuel air with a greater intake.

2005 XLT Triton V8 5.4L, I've put on a HBS 2.5" level kit, which was about the most challenging and scary thing I have done to my truck thus far.

Any help would be greatly appreciated, now I am going to do some searching to read up on all of this a bit more.
