Long time listener first time caller that's a lie I've never listened to day in my life I've been doing LS swaps now for a few years and I need to get into being able to tune and I have no frame of reference for any computer skill or ability whatsoever I'm currently in the middle of a 0411 swap on my 99 GMT 400 and I am completely lost as to what to do to tune my ECU or to even get the right OS on my s*** any help would be greatly appreciated
