Ahh so that worked out perfectly for you...that would have been nice, then I could have just compared normally. But I think especially comparing backwards, it's definitely a noticeable difference!
I've been telling a lot of ppl about it, and many ppl just don't understand the significance of .5 seconds when you're even close to 4 seconds. They think it's crazy to spend $2k to gain that tiny bit of time 0-60. You have to explain how it's obviously completely different than going from 6 to 5.5 secs, or even 5.5 to 5. And it's not all just about 0-60...the HP and torque increase is significant.
I don't think I will last a week...
