are there any aftermarket throttle bodies that wont require custom tuning, ive heard mac with the adjustable screw wont need one.

 

aftermarket mass air flow sensors need custom burns, throttle bodies do not

 

even granatelli's maf? thought they were calibrated not to mess with ford ecm.

 

- after any aftermarket maf is installed you should dyno with a wideband 02 to get air -flow readings

 

an expensive tool for a do it yourselfer. installed a aem brute force intake and the maf is the smallest part in line to the throttle body. looking to purchase one but hate to burn my new superchip. hoping the granatelli would work

 

If you use a calibrated MAF by itself its usually fine. If you use it with a chip you need to get a wide band O2 graph because its probably going to be too lean with a standard burn.

 

what would be the rough cost to burn a superchip for a maf sensor on a v10?

 

I don't put prices on the forums (except for specials), trying to keep it from becoming a catalog and instead keeping it as an information source.

Hello Ford Bros, I see that you are talking about 02 and lean burn, I and issue and I hope that you all my be able to help me out.

My 97 F-150 has over 119,000 miles and I have add coldIntake,75mmTB,MAF, F.M. catback,w/20in shoes and I'm now adding a stage 3 chip.

Will I need to change my stock 02, and if so change it to what?

Thanks

be a good idea to change it out- and have it dynoed with air fule wide band done on it so ken can richen tune for that aftermarket maf

 

You don't need to change the O2 sensor unless its gone bad from either failure or extensive rich burning for a lot of miles. You need the computer programmed for the mass airflow sensor. The chip needs a custom burn, and wideband O2 reading on dyno will help a lot but is not 100% required if you have a calibration sheet with the MAF.

 

Thanks for the info.
