The heater lines are probally 1-3 HP
DONT TOUCH the mass air flow it will only cause problems
but if you P&P the TB it will give you around 10 HP and better throtle response

a friend of mine had a granatelli maf (looked like a descreened gm maf)....he was having problems so he put the stock one back in and the car ran 100times better. thats just one case though, im sure some people have had good experiences with them...
