I added headers, exhaust, a throttle body, spacer, and a
cold air to my t bird. I also deleted the cat. The car seems
to bog down. Do I need bigger injectors? Another intake
manifold? What should I do next?
Don't know what you have in there to help. What size engine? And how many miles on it?
It's the 5.0 302 There's 39000 miles on it.
