telling you from actual experience in this. The trucks mass actually helps it out in the higher speeds. Think about this bonneville salt flat racers add massive amounts of weight to keep vehicle planted at high speeds. My truck at 160-170 felt very stable. Also weight of truck is going to help load that 88mm a good bit especially with 323 gearing
that z06 isnt no 1500 lbs less. LiL Sis is 4400lbs with its owner in it. Owner is 135lbs… That z06 with its owner is probably 3700lbs. A difference of 700lbs but down on power and torque. Lil Sis at 25psi is probably around 1100 torque
