Well I was trying to sleep in after a late night going to bed at 3. Well I get woked up by a doorbell, who could be wanting me early at 8AM. WTF, am I awake, the Post Office guy? So I sign, and when I open my eyes more I realize its the sprint booster. So I say what the heck I'm already up. I get the thing installed, takes about 2 minutes. I put it in and I notice my RPMs are revving from 1-2 constantly. I get errors on my i-drive with engine malfunction and cruise control fatal error or something.
So I try to drive the thing and it just jerks like crazy. So I take a recess, have breakfast to think it over.
I take the pedal off again and disconnect and reconnect it. Start it, engine isnt revving before and no errors, yay.
I take it out for a spin, and first impressions, holy *hit. The 525 doesn't have the most power, but with this thing it feels like a total beast.
I drove through the neighborhood a bit, and I already know this thing will be getting me tickets. Speed limit is 20 and I find my speedometer at 60 somehow.
But the mod is definately worth the money, my only main concern is, does this damage the engine over time with the high revs? I think I gotta get used to this thing first before jumping into the weekly traffic which I always face if I don't want to get into a accident with the added thrust.

In time, you'll learn how to adjust your accelerating habits. Surely you won't be driving like a beast everywhere. But it's nice knowing that when you need to mash on that pedal, she'll go

I have never heard of such a thing either, but sure enough the USPS guy was at my door.

How easy was the install? Will it void BMW warranty?
I haven't had any issues with warranty... but I'll let the others chime in regarding their experience.
