getting a dyno tune, what can i tweak?

[bigneilsen]

Hey guys,
VT II SS, its going in for a MAFLESS dyno tune next friday and to get my moneys worth i wanna know what can i get them to tweak for me.

For example i wanna raise the idle to 8-900rpm.

obviously ill leave the important stuff to the tuner (spark tables, air:fuel etc.)
does anyone know or is there a list somewhere of the parameters that can be customized they way id like it not how to tuner thinks ill want it?

you can get the line pressure raised in your transmission if its a auto... it gives it a firmer shift

If you want to change parameters yourself maybe you should buy the tuning program like LS1edit

yeah gearbox line pressure will be upped. but because i dont know much about what pressures they usually run at ill let the tuner do that.

yeah i thought about doing it myself, but id still rather have a professional to tune it - seeing as ive never tuned a car before
