hi im having trouble.. u see i have my 2003 svt cobra but i ordered a new pulley a 2.75 with trk6 spark plugs and a intake.. it also has a cat back exhaust.. where do i start? i know how to do the basic stuff but what about the detailed tuning with the spark, lean and rich and all that? i feel like my car is running lean if im not mistaken.. any recommendation on how i should tune it. and how much hp do u think i will put out? can u be specific on what areas i have to adjust? and how much?
