I told my programmer my tire size was 26" when its really 29" and now my speedo is out but the rev. limiter cuts out at 3200 ( redline ) and man does she fly I had to be doing 120 mph+. If the tach stays the same i know that 1900rpm is the speed limit , at 1900 now my speedo says i'm doing 50MPH, has anyone else played with this ? is there a chart that i can use so i know what tire size does to my speedo ? and when the hypertech asks if tire size is factory...what is factory tire size in inches ?

i often thought that would be fun to make it go faster without actually using a speed limiter delete.

I wonder why hypertech never figured out how to remove the speed limiter when predator and bullydog can.. Maybe they just didn't want to?

Tell you what it is pretty cool looking down and seeing the speedo at 120... And got there in a hurry too.

According to what they told me, they can, but they won't for liability reasons.....

That was what I assumed as the reason they didn't want to...
