when i get a leveling kit and about 33in tires should i get a programmer to reset the computer? wont the larger tires throw off the speedometer or something? it will give me some hp and better gas mileage right?
Yes, a tuner like the Diablosport Predator will correct for larger tires, which will bring your speedo and odo back to correct. This will also help your shifting a little.
The extra power CAN help produce better fuel mileage by using a more desirable timing and better fuel pressure, but often times this is offset by the shear fun of having that power available. Bottom line, if you baby it, mileage will come up, if you hammer it, mileage will stay the same or slightly drop. Takes fuel to make power.
Bang for the buck, the Diablosport is about the best bet.
yep thats all you do but the one thing you wanna watch is don't do anything that wold make it try and comnicate to the computer such as opening and closing the doors and having the radio going and watch that no one sits in the passenger site since they have a air bag sensor in the seat..
