!!!!JB2 installed what a difference!!!!

lemme first say the install is not at all as easy as it look's.Disconnecting the dme was hard...putting it back on was twice as hard also taking off the ecu cover was quite hard


but well worth it the power gains are tremendous the 3rd gear pull is like a rollercoaster taking off

1st gear floored INSTANTLY jumps and bounces off rev limiter

2 gear spins forever

shifting to third and having the chair slam againt your back is AWEEEESOMMMME

4th idont know because iam already going way to fast but the power is there

the car is not fully adapted yet it's only been about 3 hours


but guys n gal's this is worth every dollar

if your hesitating on the jb2 DONT its worth it enjoy it for a couple months save up some cash and getta jb3 nbd




all in all great product

If you like the JB2, you should try the JB3!

Lol wayy exaggerated or I'm used to mine. While you feel the difference its not that big. From a 60mph roll to 120 its only about a car length faster.
