Hello to You and Welcome to 94-95 StangNet
Those store bought chips don't work all that well in our Stangs
If you got a gain AT ALL ... most likely 5rwhp or less
so
A mod such as that ... its a terrible gain for the buck spent
A few more thoughts for you
The intake manifold is a great idea to make more power
however
That 65mm tb is gonna fall in that same category as the chip
Reason is cause the amount of airflow generated by your combo
at this time is just not enough to render your OEM 60mm tb
as being ineffective ... Even With The Upgraded Intake
Now later on ... if you swap parts out such as heads, cam, and
headers which will allow more air flow ... the larger tb would
be more effective
I'd stay with your OEM tb for now
Just trying to help you see you can spend B I G money
and
Gain very little performance
Since you say you are new to this hobby
You might find this to be helpful
