Hi,
In 4days time I will be taking my car to its first dyno tune.

Any tips to what I should ask for or what I should look out for - if there is any.
Or should I just let the "experts" do their thing?

Great forum this is, bye the way...

 

ask them to hook up the wideband so you can watch your AF ratios.

 

are there any mods done to your car? like engine wise?

 

At the moment, basically nothing.
Only a K&N flatbed airfilter. - car hasn't been on a dyno since.

I also read that changing from 97octane leaded fuel to 95octane unleaded fuel can cause your timing to go out.

so i just want everything sorted for the moment...

 

Honestly you dont need to Tune the car, the dyno will just let u know the power youre putting down.

 

how come you running leaded 97 fuel on a street car without boost? I would just run the cheap crap if you dont have to many mods done to the engine.

 

its not the same octane sytem we have here. thats closer to 93 in US octane.

 

but isn't the car getting more air than before, and therefore the a/f mixture isn't correct?
