I purchased a Granatelli Big G Flash Tool for my 2002 Camaro SS. I install it and it adds power BUT my speedometer stops working after the install. The speedometer needle won't go past 10mph even when I'm going faster then 10mph. I will uninstall the programmer and my speedometer works again. The install instructions were not very good. I've had my SS for two years and I bought the programmer last summer and never got it to work. Can any one give my some advice to get my programmer to work?

Thanks

Have you tried contacting Granatelli?
What made you go with that unit rather than some of the more popular and well supported handhelds like the Predator?

I would give them a call.
