for the price it costs to get a tune i'd be looking at spending it on other mod's first, rockers would be a good easy bolt on mod to do,...

Is it supercharged or naturally aspirated? If it's charged a few simple mods and a tune will set you flying but if it's naturally aspirated (Ecotec) then it may be a bit futile spending on a tune imo
