have you used the chip or know about it? i heard ppl get 20ish hp gain from one tune and 4 to 5 mpg on another. is that just plain Bull$%^*?
If you are talking to me
I'd not know about that chip
but
I have had a bit of experience with tuning a 94-95 Stang
With such a combo ... you're not really moving all that much more air
and the OEM fuel system is more than cabable of dealing with what
additional air flow you are now generating
That means the fuel is gonna be pretty good as the OEM inj's
and meter are still in place
When you see a tune make more than a subtle difference is when
the values in the pcm are a good bit off due to mods that have
increased airflow substantially
Of course ... you need substantially more fuel and the tune will take
care of the additional air flow and fuel requirements
I can say for certain with a mild combo
I can make a differnce that will be felt for sure
but
The difference would be from things like
tip in retard killed
spark curve modified to produce torque quicker
fuel optimized
and other little things
Here is the thing about such a combo with the tuning I speak of here
Yes ... you would feel a difference
but
You would not see all that much more peak power if on the dyno
What I'm trying to say is ............
I have complete control of all pcm settings and I can datalog for
fairly detailed verification for a specific car ...
Is some generic chip gonna do more than that
I think not
and
If it could match it
It would not be all that much ... 5 maybe 10
Again ... we're only talking bolt on stuff here
so
The tune ain't gonna be all that far off
Now as you generate a good bit more airflow ... things get outta hand :Word:
You need fuel to keep up with the airflow
That means larger inj's & meter so the fuel will be outta whack
