thanks elmariachi. the reason why i m asking is after adding the sprintbooster, i experienced 2 'uncomfortable' ride feeling. i am thinking if the coil booster would help.
1. my ride redline without hesitation (which is great!), i almost feel like there is no such thing as low-end torque already as i will always be above 2-3 rpm most of the time. so i am wondering where would the smoothness comes in with the coil booster?
2. sometime, on revving, i would totally removing my foot from the accelerator. somehow felt that the engine gear 'stucked' at 3rd gear and car suddenly felt 'draggy' at high 3-5k rpm. funny feeling, but got used to it. (bo bian, heavy foot) would the coil booster 'normalize' this uneven draggy feeling?
