My car seems to bog down and I'm wondering if I need bigger injectors? If I change my injectors, will I have to upgrade my air mass meter??

Doing all this, would I have to have my Diablo chip recalibrated??

My mods are in my signature. If you guys can see something that could be done different or that would benefit me, please let me know.

Thanks in advance!!

Amy

well if you get bigger injectors (which I don't think will help, JMO) your mass air will have to be recalibrated to the size of the injectors...so yes you'll need a new mass air. And I do believe that your Diablo will have to be retuned with the new mass air and injector sizes.......hope this helps....

describe more about the bogging....

Just seems like since i ported the heads, i've lost low end torque. i upgraded my gears from 3.73's to 4.10's thinking it would help, and it has..some. But, it's still feels sluggish. Something isn't right..maybe i need to change my spark plugs???? I'm clueless

Any mustang pushing over 300 horsepower needs 24 lb injectors, and with the mods you have and ported heads I am pretty sure you have more than 310 horsepower.Yes you will need a new Mass Air Meter but its better to buy one then to let your car run to lean and damage your engine. Change your plugs too.
