Even with this engine should I expect my car to run only a little bit faster than it used to even though I have an engine with the potential of 350+ horse.I am using the stock TBI and stock computer.Is this lack of power to be expected?I am just running it with the stock TBI while I get it broke in.also the stock exhaust with a gutted cat
