it's a 500-700 dollar ecu, depending on whether you get the "plug n play" or not (I have no idea what the difference is) and it ups your hp to about 400 hp...I also believe there is a switch that you have that can make it drive like 'a 328' if you want it too, thus saving gas and putting less stress on the turbos...it's really a great investment...essentially makes your 335i an m3 without the badges and prestige that comes with an m3...I hope to get a 335i in the spring and add it
My stock mustang that only has one map will yankify you.

im debating whether to get an HPF stage 2 M3 or a 335i with JB3.
The only problem is the fact that if I get an HPF M3 it will be an 02-03
If I get a 335i with JB3 I can prob. get one new or slightly used.
What would you guys get?
