Default Time for a tune

I am going to be sending my computer to pcmforless.com within the next couple of weeks and i need to know a few things.

1.on the order sheet under "engine" it ask for information on the cam, intake, and compression. Sence it is all stock what do I fill the blanks in with?

2.Trouble Codes - I am going to be removing my AC and Powersteering. Do I need to know what the trouble codes are or do I list it that they have been removed?

3.Drivetrain - I have a CPT PRO RACE built transmission. Do I want to modify the Shift Firmness or leave it as is?

4. I live in fredericksburg, Iowa. Is that considered high altitude?


thanks

As far as I can see I don't think you will have to do anything to the pcm for those mods. I would however do the firm shift points. Did it on mine and love it.

You can also pick up power even stock because the stock a/f ratio is rather rich.

The line pressure in my transmission has already been increased so it already shifts firm. I know some transmission builders don't want the shift firmness changed with the computer due to the fact they have already changed it when they built the trans.

1. Id put" stock" in those blanks, under your "engine" catagory.
2. I dont believe you'll have any trouble codes, but it wouldn't hurt to put that on the sheet, just to let him know anyway.
3. I would leave the shift firmness at stock. If your trans is rebuilt, they most likely put a shift kit in it. The more you up the shift firmness, the more line pressure you get, in-turn, creates more heat....which you DONT want in those transmissions. Excess heat will shorten the life of the trans. SO, a tranny cooler would not be a bad suggestion
4. No, your not in high altitude.
