Wider selection of tunes would be nice
Of the included tunes, only 2 do not require premium fuel. A high mileage, and an 87 tune. Of the two, I really can't tell much difference between them. Both do speed up the gear changes and feel a bit more torque, but the fuel economy in the high mileage tune is no better than stock. Fuel economy in the 87 tune is also not much different from stock. A wider selection would be a good upgrade. As to the hardware, it is easy enough to use, if a bit slow. About 15 min to load a tune in 5.7L Hemi
Works as advertised!
I finally pulled the trigger & bought this afe booster for my 335i f30... there's a refund option so I figured why not... try it & return it... i tried it & im never returning it. This should be a 1st mod for most cars. Makes it more drivable, more fun, maybe the way the way the throttle should have been made. The price is high but it is worth it. No added power but it make u feel all the available power more instantaneous. Buy it cause u wont return it.
