Funny on the timing of this post, I got this email today from ECS. I turned away immediately when I saw that this was $300. Kinda pricey IMO, at $150 I would be somewhat interested.

Isn't the "POWER" button = Sprint Booster?

Sprint booster increases the sensitivity of your throttle pedal.

I was thinking the same thing.

The throttle response at 5000+ rpm is absolutely razor sharp. I have read good things about the sprint booster on the cars with the N63 that has a bit of lag, but I honestly can't imagine this being worth it on M3

I had one on my Mini Cooper S and it was well worth it for better throttle feel and rev matching. But I don't see the point of it on the M3, especially considering that's what the Power button basically does.

Works awesome on the E60 M5 side. A lot of the guys have them. I thought the same thing about it being the "power" button kind of thing. But it really firms it up in all modes. I think its a worthwhile mod. I personally leave mine in green (sport) mode. The red mode is super touchy!

worthless it's exactly what the POWER button does already. It may be a different throttle curve, still the function already exist, because of it, it's worth $5. IMO.

I had a friend who loved it in the e60 m5 too, but the difference between the Power button in the M5 is that it actually does add hp.

So not one person has tried on an M3 yet?

"Funny on the timing of this post, I got this email today from ECS" Me too, that is why I posted.

I got my 2011 manual M3 coupe earlier this year. Was disappointed with the throttle response. I came from an E46 that had the sprint booster. Always liked the SB. Placed it on my E92. Much better throttle response and then hit the m button! I much rather drive the E92 with the sprint booster.

I had an E46 M3 with one installed but didn't like it after I had the car tuned. I tried it on my E39 touring and rather like it on the M54 .

I have one as well and it does make the throttle react faster than stock. Even after my bpm tune which modifies the response, I kept it and it seems to work well with that tune as well.

Get a proper tune. Not a plug in.
