Here is my dilemma though. I have tried both the wrx and the FXT speedo gear and both are off. wrx is off by about 13% and the FXT is off by about 7%. The FXT speedo is still off becuase the FXT runs 215/60/16 which has a diameter of 26.1 inches. The 235/40/17 I am running has a diameter of 24.4 inches. So does anyone have any recommendations on what speedo gear out to get. I have no problems pulling down the transmission again, just want this right as it makes tuning a nightmare.

And recalibration is not an option as this time because the speedo and the ecu both work off different wires from the sensor from waht information I have gathered. And i have not found the variable to adjust the speedo in any of the tuning software I have tried.

I talked to the guys at Andrewtech about doing my LGT gear swap, including the 4.11 FD. I also asked about a speedo gear, since my stock on wouldn't read correctly. They said that they would custom make one for $85. Should work for you as well.
