I had just finsihed the airflow sensor mod on my truck, the one where the middle bar was removed, I did not hit or mess up any of the sensors, i removed them before i began working on it, when i got it cleaned up and put it back in, my acceleration from 0-60 in really slow now and yes i did make sure all of everything was plugged in.....anyone got any ideas?

You didnt put it in wrong...You just cant port the MAF with the stock sensor. It is not calibrated to handle the new airflow rate. We tried this at the shop, and it made the truck run like crap. If you want a bigger MAF, youll have to get the granatelli.

Not true. In the case of a S/C , yes, this outflows what the stock one is designed to handle. The stock MAF can handle and airflow rate up to 650 CFM and taking out the center and screen doesnt give it more than 50 CFM difference.

Alot of times it the intake set-up. Its not smooth enough for such. The divider is the along with the screen to reduced turbulance , and sometimes from the experiences I've had doing this mod, have had the same problems you have. Certain intakes dont like this, it screws with the vaccum created and causes a negative turbulant airflow. The only ones I have not had problems with and do show very good increases in the K&N 2 and the Volante.

In the case of the of our test truck (it happened to be my own personal truck) it wasnt supercharged (and still isnt). We cut out the divider, and ported it on a lathe. I dont know how much more accurate you can get without some expensive tooling.
