ET Streets/speed correction
ET Streets/speed correction 
I am still playing with my programing to get a correct correction in m computer for my 26x11x15 ET STREETS, which actually measure about 27 inches on the car. That is almost a two inch increase from my stock 275/40/17 SS rims/tires. At the track i lost ET due to this. Does anybody have any experience with this? Do i raise my MPH AN RPM on the shift points to trick the computer 4-5mph difference? I did this and tried to tell with my G-TECH meter the difference but i cannot be sure until i get to the track again. I did order gears and a converter to fix this problem soon but i just want to see if i can get some of the speed back by programing until i get them installed. Thanks. 
I found some tire conversion charts online and played with the numbers. It looks like 279/55/15 is the closest to my 26x11x15 ET STREETS so i will program that in along with a 5 mph increase in my shift points and see what happens.
