90 MM TB

3.1415926 * (45 * 45) = 6361.73
(90 * 10.168) = 915.12

6361.73 - 915.12 = 5446.61

102 MM TB

3.1415926 * (51 * 51) = 8171.28
(102 * 10.168) = 1037.14

8171.28 - 1037.14 = 7134.14

Now the ratio:

7134.14 / 5446.61 = 1.310

the the tunes base ETC Scaler: 5636 

Multiply by the ratio:

5636 * 1.310 = 7383.16

The 5636 # appears to be pi * r^2 * .8860 (88.60%) so if you multiply that:

(3.1415926 * (45 * 45)) * .8860 = 5636.49278  so that is pretty close...

Now, I know there is ETC Tip In Limits, Fast Torque Exist, traction control

Just wanted to make sure I understand this and if this should be the only 
change to get the 5" CAI and 102 MM NW running.

The tuning schools says to do 102/90 and use that ratio to multipy the 5636 value

Which is 1.1333333333 * 5636 = 6387.4666 (4 decimal places) or rounted to 6387.5000.

I'll have everything on Thursday so should be ready to go Friday if you have time...

Thanks!

ID of ADM intake is 3 7/8 so to MM is 98.43MM 

so pi * r^2 = 6151.43 for the area of the ADM intake ID

ID of RDM 5" is 4 7/8 so to MM is 123.83 MM or 124MM

so pi * r^2 = 12,076.30

12076.3 - 6151.4 = 5924.9 and that is the total area increase so, the % is:
5924.9 / 12076.3 = .4906 or 49% larger!

The ratio to multiply by would be

12076.3 / 5924.9 = 1.963

yikes!
