This is people's problem (noobs). They assume that if they put these tunes on their cars they will be able to run the exact same times. What people don't realize is how many times we have to try to get a time launch and shifting correctly. Sometimes you will get one good time launch out of 30 or more tries. Another thing to is some of these tunes may not respond well on indy. All of us have different methods of tuning and dragging. This is what seperates top tuners from "draggers", we tune these cars then you copy the tune and never learn what we had to do to get these times. I will always say the samething I rather be known for my tuning skills then my dragging skills. Most of these so called "fast guys" can't tune for the life of them unless it's a car we see a million times in the strip i.e acr, no stripe, gtr b.e which tunes are avaiable in bunches.
I have seen plenty of people use my tunes and when you asked them hey what does that car run they say I don't know or i just tuned it lol.
