How much HP do TBI's make at the wheels?
My friend owns a 89 Firebird Formula 305 TBI with a K&N and Flowmaster Muffler...
He thinks he is making like 200 horses at the wheels..Which is a bunch of BS.

A4 cars should put down between 130 and 160. Age, wear and the state of tune of these cars cause the huge variance.
When I first got mine it dyno'ed around 147rwhp and 280 rwtq. L03s make good truck engines, loads of torque down low, but no legs.
