Surprises me nobody can read the print - street tunes for trucks only. This is because trucks don't like to be dyno'd over 98mph and some break driveshafts.
I'm still surprised how many people don't go for tunes. Most often doing the full tune finds big problems. A ton of people drive around with LS cars down 50+hp thinking the cars are fine because no engine lights. Just did a car last week with 20k miles.Car street tuned fine but on the dyno it valve floated big time above 3500rpm.Street tune didn't see it. Fixed the springs and gained over 100rwhp.
