8mpg in the city lite driving, almost a stock engine with a lil baby cam and the holley c950. i dont understand why i have such shitty gas milage. car run good. i had a shop tuned it, but i think i have bad iac, i waste aot of gas just starting up, alot of cranking. it doesnt smell or seem too rich. i was thinking leaking injector or some how tune is wayyyy off. no clue.

 

You answered your own question

 

i cant see wasting that much more gas just starting up, i know it is using more but still.

 

Look at the bold in lo-tec's quote. I think he was referring to your carb.

 

its not carburetor, its fuel injected. that the stand alone ecm

 

If the car has a cat it won't smell rich at all. Check the O2 voltage while you drive around or check with a wideband.

 

Yeah something is def wrong with your car. With my setup in my sig I can consistently get 20mpg. Bone stock 350 would get in the neighborhood of 26-28 mpg

 

I would have another shop tune it then. My POS gets a minimum of 15-16 mpg, and I DO NOT baby the car when I take it out.

 

Aggreed. My 357ci has a 750 DP Holley, 200cc heads and a cam that sounds disgusting and it still gets double what you are getting. Its not tuned right or something else is very wrong with it.
