2006 Chevrolet Silverado 5.3 Z71-Gear swap now abs code ....

[spl]

Installed 6 in RC NTD lift on truck and 35" tires a yr ago, saved up and recently did gear swap from 3.42-4.10 ring and pinion,Shop calls me and said I have a bad abs sensor on front left,I say never had a light before??? turns out it popped on during their test drive after the gear swap.. After finding this forum and reading all I can find,This seems to be common...They replaced the sensor as a courtesy ,but same problem and code pops up after you drive a min . I am told the problem is due to the difference in rpm from front wheel to vehicle speed sensor in trans case. wasnt a problem with big tires only,just after gears swap,they say trans case output is turning much faster now,thus increasing the difference between the readings from front to rear .. I ordered a Hypertech programmer as I have seen rec on here,fixes speedo and you can adjust for gear ratio,but does not fix abs issue,FYI. So I just ordered Dakota digital SGI-5 Universal signal interface unit,Looks as though,you can take VSS output wire and decrease or increase the pulses to fix this issue... Anyone here have experience with this???

Did that with a Hypertech and it got the speedometer right ,but the abs light was still triggered just like without it.....Prob is,my truck was not available with a 4.10 option.....so unless Im wrong there cant be a "program" for computer,right???? truck is strong now!! shifts great all is good except speedometer is 8 miles an hour faster than its actually going and abs light and bell....
