I read in another thread, someone telling the person to get a handheld tuner (SCT) and then dyno tune it. What are the benefits of that, if your 'stang is otherwise completely stock with just gears and exhaust (no headers)?
You can adjust for gear changes and turn off rear O2 sensors with regards to gears and exhaust. Other than that I guess timing advance and tuning auto tranny shifts. Also you can read and clear error codes. Theres some other things such as air/fuel and coolant temp. Do a search for "xcal" and/or "predator" and you will get a feature list.
If you have a power adder or extensive mods, sure. Go for a dyno tune too. For a car that's stock with just gears and exhaust, you won't see much more from a dyno tune. You may gain some but that money could be spent on other things like tires or suspension mods.
Yeah i agree with propellerhead. I dont know what kind of mods you have, but until you get to pretty much the same mods i have in my sig, you dont really need a tune or a hand held tuner. But they are handy to have!!
...speaking of which i need to buy one and get a tune!! grrrr.....
