This is a little thing to anyone who wants to have a car more powerful then a tune describes. This was tested on the F430 Stradista. When I try to get my cars ready for tuning, I notice that I sometimes overpower and make the car's tune worthless. Well, not anymore! I have used my math skills and I have found a way to make the transmission the same, or even more powerful.
Correct tune:
Transmission
Set Final 1, then Max Speed, then Final 2 + individual ratios.
1st:-- 4.139
2nd:-- 3.037
3rd:-- 2.367
4th:-- 1.931
5th:-- 1.603
6th:-- 1.390
Final: 4.300/2.500
Max Speed: 124 MPH
Top Speed overall: 222.
But, What I did was take the numbers down so I know how far off the gears were. I got these numbers.
1: 1.395
2: 0.844 - 0.002
3: 0.533 - 0.026
4: 0.350 - 0.046
5: 0.230 - 0.017
6: 0.362 - 0.212
In that, the first number is the difference off from top and bottom. The second number is how far away it is from the bottom. You will see what I mean after I put the fully powered one out.
Overpowered tune:
Transmission
Set Final 1, then Max Speed, then Final 2 + individual ratios.
1st:-- 4.253
2nd:-- 3.117
3rd:-- 2.426
4th:-- 1.976
5th:-- 1.641
6th:-- 1.422
Final: 4.300/2.500
Max Speed: 124 MPH
Top Speed overall: 222.
How is this possible? I will explain that now!
The overpowered tune is alot more powerful and stronger then the RKM tune, but it still has the same Top Speed. It is simple of how to do this. 1st gear's area is 4.225-5.648. The original difference was 1.395. so 5.648-1.395 and you get 4.253, same as the over powered settings. Another is 6th gear. the distance is 1.202-1.572. In this, the equation goes like this; 1.572 - (0.362 - 0.212) = 1.422. These gears are the same place and structure as the original tune. Another step you can take with this is the more advanced tune, or the "RKM Overpowered." All you do is take how far off it is from the bottom and bring it out that far. Here is what I got from that.
RKM Overpowered:
Transmission
Set Final 1, then Max Speed, then Final 2 + individual ratios.
1st:-- 4.225
2nd:-- 3.100
3rd:-- 2.415
4th:-- 1.971
5th:-- 1.636
6th:-- 1.414
Final: 4.300/2.500
Max Speed: 124 MPH
Top Speed overall: 224.
With the correct sight adjustment for the ratios and not the picture, it would look like this. All you do it take the equation from before like in gear 6 and it would look like this after swapping the top gear for the bottom of the gear; 1.202 - (0.362 - 0.212) = x+0.362. You will need algebra to solve this. All you do is subtract 0.362 from both sides. It will look like this.
1.202 - (0.362 - 0.212) = x+0.362
-0.362 -0.362
In the end, you get this;
1.202 - (-0.212) = X. With the 0.362 gone, it becomes this; 1.202 + 0.212 = X. With that, you can determine how many spaces you need to move. For this, you need to move 1.414, which is the same number as the 6th gear in the RKM Overpowered. With this, people won't need to fear if they overpower their cars for more power. So, lets go over it one more time to put it all together at the bottom to make it easier for people.
I hope this will help those who want to keep the same tune and not get frustrated over not wanting to have their car not have enough power.
This took me 4 hours to go over and I made sure all of my equation were correct. To everyone who this helps. Your Welcome. There is no need to thank me for anything since I normally was going to make this for myself.
Even though I can't get my head round the maths, I can understand what you have done and how to do it. Definately a big help to everyone, so thanks a lot! 
Now if you'll excuse me, I need to cool my brain down from reading all those numbers. 
Sorry to steal your line.
Too bad my Golf is now back to its normal state and I don't have a spare Maziora Seyfert paint chip
