time for a tune??

[viridionplague]

so im wondering, if it might be a good idea to get a tune

the car has headers, cats, and magnaflow catback, air pump delete, air box has ben removed as well

this all all that i know has been done to the engine but there might be a thing or two more done that i dont know about

however the car seems to be running rich, least i think it is, so better gas mileage maybe?

and the best gas i can get where i live is 90 octane, as i live in a small town now


just wondering if it might be a good idea to get a tune dont to adjust for the octane and maybe pull a few more ponies out of it as well as get some baseline dyno numbers as well

If you have money laying around, and want a dyno baseline before heavily modding it later, then sure get it tuned. If you dont plan on modding it further, then judging by what Ive read on here, and asked these folks myself, dont worry about it.

 

[sage2k]

do you have a soundclip of your car? id like to hear it if you can post it

You've done next to nothing to your car so I would not worry about it unless you are that anxious to see what it puts down. If it were me I would put that money into some more mods. Not worth it.

I agree with the others ... Not enough gain for the money spent :Word:

I know most jump on the exhaust for first mods
but
With a focus on ... Power Gain ... for a stock Stang

Exhaust mods are a piss poor gain
yet
They are a mod that makes your Stang sound better

Hey ... join a Mustang Club and get in on a cheap group rate dyno day

That way you can get a baseline with just a few bones spent

What kind of mileage do you get?

I get 18 (mostly highway) and I have thought about the tune jsutifited jsut by the potential gas savings...

However gears are better than a tune...

Our cars are supposed to run on 87 octane. (Most guys run higher octane to avoid the dreaded 94/5 engine ping.) So, the 90 that you can get should be good.

You say it seems to be running rich. Have you attempted to find out if it really is and why? That's where I'd start. What IS the mileage and what type of driving? How many miles are on the car? Have the O2 sensors been changed? (Due at 100k miles.) Are there any other drivability issues?

If you want to get more mileage out of your car, I'm sure you can find info on how to do that here on Stangnet, if you search. You can use synthetic oils throughout the driveline, proprly inflate the tires, use extreme care with the pedal on the right, etc. Lots of stuff.

Another thing to consider is the gas you use. I used to go to a "Clark" station near me. With their gas, I could get 240 miles out of a tank (1985 Toyota HiLux. 10 years ago.) When I used a Shell station, mileage went up to about 290 miles on a tank. Same driving, same trip. (I filled up for a 30 mile commute on Monday. With the Clark gas, I'd have to fill up again on Friday morning. With Shell, it was Friday afternoon, on the way home.)

Let us know how it's going and any interesting info that you find.

i got the car with most the mods done already, ive only done the rear end and suspension, yes it has gears, 3:73, forgot to put in sig though

but it says on the gas door to use 92 octane, the best i got in town is 90

and it seems that when i drive to the cities that it takes almost 1/4 tank more gas than it did 3 months ago, (used to be a hair over half tank, now its closer to 3/4)

as of right now i do use it to deliver pizzas in a small town, so i try to be nice to it, shifting at 3k, i also use synthetic fluids already

the car has 93k on it, i do not know about the 02 sensors i would assum they havent been changed

i also have no real way to find out if it is running rich



so im my mind the benifits would be,

baseline dyno run,
should result in better mileage
a few more ponies (not alot but a few)
and a decent piece of mind on where my car stands (problems or not and that kind of thing)

as for power i got a 408 in the works, i know dynoing a 302 and a 408 are completly diffrent worlds however,

my butt does not know the diffrerance in where the power comes from, just that its their

The problem with your thinking is that no reputable dyno/tuning shop is going to run your car, if there are mechanical problems. Those need to be fixed, first. It would be a waste of expensive dyno time to get it up on the wheels and find out that it needs a fp regulator or O2's or something.

You really need to start with a mpg figure for your car, since that's the problem you are concerned with right now. Sounds like you do some city and some highway driving. You should see 16-18 mpg, with what you've said. (Already synth and light throttle use.)
