After doing some searches on my own, I have only gotten more confused about engine managment for a turbo'd rs. I don't know if i want a full stand alone or a piggyback. Which is better for the "home enthusiast"? I like the link system cause i don't need a laptop(i think) because u can buy for a small price that lcd display tuner link instead of a laptop.Right? The link can change a/f, boost, knck, and ect. I also like the J&S safeguard. Altough it isn't "tunable" it does most of the work of knock control for me, since i am new at this. Also, it is drastically less then the link. I want to turbo my rs when i get it, and i only want to run 4-6 psi of boost. I also want to get the most outta the car without recking the engine or drastically reducing the engine's life span. If it doesn't seem like i can meet these goals, i guess i will stay n/a.
