1. You may have a vacuum leak on the GT40 intake installation.

2. The Granatelli Mass Air sensor may just be too big for your application (stock heads & cam).

3. Is the new Mass Air sensor calibrated for 24-lb injectors? If not, that's your problem.

4. You don't need 24-lb injectors.

you are OVERINJECTED!!!

if your car is NA, then 24's r too much for stock heads/cam. If u have made some changes and your car is making more power u can raise the fuel pressure to get more fuel, but u r running way too rich now. you should go back to the 19's or lessen the fuel pressure. Make sure your MASS airflow sensor is calibrated to 24's or its not going to run right.

well i guess i should know by now not to believe everything you see in jegs.i hope the intake works because of the seperate tubes my car slows down when intake is hot.big trouble in late rounds!!!!!!!!!!!!! but i will go back to 19 injectors and stock mass air.

There is no need to switch back to 19's. Just make sure everything else jives and you will be good to go. Keep the 24's... they will be extra insurance when you get some heads.
