with that strong wind i think on another day you will run faster

 

Ion ....Not to steal your thread...I am looking to get in the 11's with my stock heads before our track closes and was wondering if going to 4.10's from 3.73 ...will it hurt not to get it retuned??? It will be for only 2 weekends??? 2 Sat.????

 

Your car will not shift at all if you switch to 4.10s. I am able to shift mine manually even though the speedo is not calibrated because it's a 700R4 and it's not computer controlled.
