40 years of pulling wrenches for a living has taught me that:

Start with the basics and use a logical systematic process of elimination.

Do you have adequate fuel? An old fuel filter will reduce your flow. Is your fuel pressure adequate under load? Put a gauge on it and verify your reg is working properly.

Did they install the right chip?

Did they confirm your AF ratios with a wide band O2 sensor/ data log after the mods?
