My speedo is off.....what adjustments have you guys made to get the speedo corrected? Do you leave it set at 3.42's and just change the "actual" tire size to 235/40 14.........or do you need to change the "factory" tire size too? I have tried a few variants with no luck.....And I know that with the 4.10's I run 2000rpm @ 70mph in 6th......40mph @ 2000rpm in 4th ect.....Please help a brother out!

have to use a hypertech or get ls1 edit to correct the computer for 4.10's oh sorry saw the word predator just now, that should also alow for changing gears in one of the options right.

I had a predator, until it was stolen out of a friends car, but before that I installed a SLP speedo recalibration unit. I know a lot of people that are using predator are having issues with changing the speedo calibration after a gear swap, well after my pred was stolen I went ahead and bought a LS1 edit license but left the SLP unit to keep calibration in check, if you cant' get your setup right with the predator I will gladly sell you my SLP setup and use edit to get the 4.10 issue fixed. Let me know.

Yeah, you have to make the change in the tire size menu.

I used the tire size change method or "temp fix" and it didn't work. The speedo is off by 10mph
