What gears do you have? They all should handle it fine, but 3.73s will be a lot better than 3.08s.

I wouldn't expect much from the fan and intake. The factory intake is a cold air intake. Look where it pulls air from. And the e fan puts more strain on the charging system, making the alternator work harder, and thus more power is needed to turn it.

I forget the p code but ABS will kick a code at 10% vehicle to wheel speed error.

Dont agree with e fan comment. Screwy fan clutch set up robs horsepower an d wired right it doesnt use any more power from the electrical system

Wait, Bigger tires roll farther with one rotation, how do you get worse mileage? Especially on the highway

Bigger tires will carry you further in one rotation but also bigger tires also weigh more & cause more rolling friction plus the increased height means more wind resistance. & mine only dropped one mpg and with 3.73 gears my speedo was 5mph at 60 I was really doing 65mph
