Bimmer Addicts,
I come from a "Hot Rod" background. Meaning high HP engine (425 rwhp 70 Nova), straight pipes and
no computer.
I was wondering if it is necesarry to unhook the battery after doing mods on our cars?
I just put on a new 'peformance' exhaust and was wondering if that is something that I should do; unhook battery for couple mins.
It is definitely 'perkeyer' on the bottom end now!

But was wondering if reseting the comp would do anything.
Thanks in advance!
Chris
