Ok, I ordered mine after reading the reveiws here and because I also hate the dreaded 1 sec delay when u hit the gas. I got it with the discounted group buy from the link posted in this thread
. I installed it yesterday and it is everything that people are saying. The car just seems way faster and practially getz rid of the delay. It's definatly not as pronouced as before. I'd say it is worth the discounted price that I paid and makes the car more enjoyable to drive. It feels like it's always ready go, where before it felt a little lazy. Overall I'm happy with it.
