I can tell you that my car saw an 20kw increase on map 2
Thats 26hp on an Australian Dyno,
I did a dyno run FBO with the JB4 turned off at 220kw / 295hp
Then turned the JB4 onto map 2 and ran 240KW / 321hp
Keep in mind you need to convert these to American numbers, add 15% or something like that.
So for a stock car, I really dont know what the gains would be.
EDIT: Just noticed you are Aussie

BMS claimed a gain of 80hp/60whp on a stock N55 car, but that sounds too high if comparing to your JB4 only dyno. I`m new to tuning, if there anything I missed?
