Alright i am just about to purchase a NX kit with the items to make it run properly. I am going to run a 50 shot. Right now i have a diablo flash tune but i have read constantly that if i use it while spraying it will retard the timing. I also heard that there is a tune you can get so when you aren't spraying it works but when you spray it doesn't(i think it goes like that). I just want to know how to get this tune and how much it will be.
