2007-2009 Suzuki SX4 RRM Piggyback ECU Auto

Definitely gives the ZUK a "kick in the pants". Dunno about the "up to 115mph"??? my SX4 AT won't accelerate past 112 even though there are plenty of RPM's......definitely get to 112 faster though LOL. SUPER EASY INSTALL!!! Well worth the $$$. Try chirping the tires without it in the automatics.
