Omg i got a reply yes!

Yes i will be getting a custom tune thats a no brainer.
Right now im just waiting on two custom tunes for the LT and gears i installed. Then i will install and get the nitrous tune ordered.
But my next question is if i get a 75 shot tune is there any way i can adjust the timing my self or with your help

to do drop down to 50 or up to a 100. With out having to order another tune.
Im all ready going to have a performance 87 oct and a performance 93 oct. So i want the 3rd to be a performance 93 oct wit nos. But dont want to b limited to the settings for just that one shot.
If i cant what would u recommend on a shot size. I dont want to go any bigger than 100 shot.
Should do some work to trans? Maybe valve body?
Any info would be much help.
