W211 E500 with sprint booster?

[i NaJ]

Hi, I drive a W211 E500 (306bhp) and have been looking into the sprint booster. I was hoping that this device could improve acceleration on my vehicle? Could you guys give me your thoughts and hopefully help me decide in whether a sprint booster is worth having?
Thanks

naj, sprint booster will give you the initial kick without a delay, not good when parking in tight spaces etc, also a little harsh, do a search on here for loadsa threads on it
