stock power
Posted: Sat Jan 05, 2008 11:01 pm
i have an 07 gmc vmax. i was wondering if anyone could tell me the stock horsepower and torque. i have a predator in combination with cold air and an exhaust. what a improvement they made.
These trucks (6.0 correct?) make right at 300 rwhp stock, and 325+ with the 93 octane tune.
Thanks
