I just got done installing my Richmond 3:90 gears in my 06 cc. After the install I have the ABS and BRAKE light on. I do not have a tune or a programmer, so I have not changed the computer yet, so is this something that can be fixed with a tune or did I miss something with the install? What is the better way to go on my truck, use a handheld aftermarket programmer, or have a custom tune done on my truck. I had a custom dyno tune done on my Formula, but I did a h/c converter and new rear so a custom tune was the only way to go, but my truck will only see gears, converter, headers and intake. Any suggestions will help.Thanks

Thats normal when you do a gear change.You just need to have the truck tuned for the gears is all.
Don't waste your time with a handheld.Ethier get a mail order tune or dyno tune.

i would definitly go dyno tune if its available to you but the reason your getting the lights is because your rpms dont match given what you are calibrated for in your previous gear size. dont worry about it
