Minor mods tune help

[jenrik]

When adding a cold air intake and a 70mm throttle body to a stock 98 mustang gt 4.6, what changes in my base tune should be made, the car isnt running well on the base tune, any help would be appreciated

Those mods on that car should not need anything other than a normal tune. Chances are on a car that old is is a mechanical issue. First thing to do is run a smoke test for vacuum leaks - and I do not mean spraying carb cleaner. Chances are you will find some leaks. The use a scanner to check for codes. Once the car is 100% it should tune fine even with those minor mods. Good Luck.
