Hey I was wondering has anyone found out about the small print on installing the 391 gears? I know it states will not void warranty , but does the dealer need to supply the parts and/or do the labour or can we just bring the car for a recalibration of tach? sounds like a real great mod for the under 550 hp cars

I believe the kit from GM performance has the voucher to have ECM changed for 391 gears. Not sure if you can do the gears yourself and then take to Dealer for recalibration. I can tell you it's a whole brand new car with the gear change especially if it's a M6.
