i have been looking around and theirs no dyno of this mod. i found some info on how this mod helps with engine respone/ gas mileage. i heard this is only worth with FI due to the power. what about a fully bolt on z?

 

Not worth the money as our ignition systems are pretty stout stock.I had one and i have the greddy twins and when mine went bad i took it out and noticed no difference.
