95 Cobra Tuning Help

The SN computers are pickier than Fox body computers, so that may be where some of your advice is coming from. Stock MAF and injectors are perfectly fine if you still have stock heads and intake. The cam only shifts your power in the RPM range until you upgrade the heads and intakes as well.

If you have an off road x-pipe, that is your smell. Even when not running rich, the exhaust smell is strong when you don’t have catalytic converters, especially with dumps leaving the fumes right under the car. At this point you really don’t have much to gain at all with the SCT chip. The old pushrod engines are not nearly as efficient as the newer 5.0 that does actually benefit from a cold air intake and tune. With your car, I would be sure the cold air intake is a long one that puts the filter into the fender well, clean the MAF with MAF cleaner spray and q tip, be sure your timing is between 12-14 degrees advance with the spout out, and enjoy the car until you go to bigger power mods. Save your tune money for after you go forced induction.

For the smell I would either put full length exhaust back on the car to get the smell going out from under the car, or change the midpipe to a catted one if it isn’t currently.
