I have seen a lot of adds about these recently and I haven't heard anyone on here talk about them. For you guys that are doing your own tuning... are you just using the Tweecer RT stuff?... Right now ive been saving for a blower and I think i want to go with a turbo so i'll be saving a lil bit more but just wondering if it would be worth it to use a EMS and my laptop and learn to tune my car and read the A/F ratio and use the features like the datalogging and so on... THanks
