Ok I have a 98 C5 I want to get a programer to get a edge at the track and my choises are a Hypertect unit or the Granatelli Big G ,has anyone bought one of these and is one better than the other I need some good input!
These are the only units out there that will tune my 98 unless someone knows something I don't know?I want to change when my fans come on and my shift points I want it to shift a little faster and harder on race day
HELP?
Id try posting this in the C5 Tech section. Id also get a real tune, find someone with LS1 edit before you buy one of those "programmers", youll be much happier.
