GOrsted thanks for the tips. As for rpms I was making a statement. In 1st gear 6000 rpm is 45 mph which is where it shifts to 2nd. I'm not certain but at 55 mph in 2nd I believe I'm at about 4100 rpm first time I pulled the trailer with this truck so not completely familiar with all the rpm's at different speeds. I was running 89 octane, I will certainly try 92 next time thanks for the tip. I am going to switch to stock 265 tires when this set wears out and deal with the way it pulls. I feel like if I put $2000 in changing gears, then another $1000 in cold air intake, exhaust, and power programmer plus have to run premium fuel, I'm getting away from the cost savings of purchasing the Hemi over a diesel. I bet with my weight 4.56 would really wake it up though.
