Need help with top speed on 4.8
I have a 4.8 Silverado with a five speed. I have looked at all the computer reprogramers and I have been told that with the M5 speed I can`t change my top speed. Is this true or can someone like MTI make my top speed faster than 90 mph.I really need some help guys. Thanks for any help.
