Guys....thx for your responses
Before we get all scientific and etc..
Throle response: Def improved
But Dyno: Def Improved
Performance: for some time now the dynolucious app for the iPhones accelerometer has been very consistent w' the Z4 Times, Stock numbers time after time were as folow: 0-60: 6.4/6.2, 1/4mile@14.8
After my little experiment:
0-60: 5.8/6.0
1/4 mile @ 14.2
Not saying those are 100% accurate measurements....However very consistent from an application and a vehicle that were tested time and time before.
Thx
P.S
......EVEN if the performance was hurt Which I DOUGHT
The sound alone makes me giggle like a kid in a candy store
