I keep seeing this mentioned in truck bios, what exactly are they doing to it , I have a 2001 4.2 v6 and ive done the air box mod allready.and was wondering what just this mod involved.

 

use the search feature, there is a long thread on this topic

 

I punched in Gutted Maf and I could not find anything, so if anyone has done this mod, or knows where this thread is please post. thanks

 

If you go to search and type in MAF, it will bring you to the thread discussing the MAF mod. I believe that it is the general engines catagory.

 

Check out the picture page at my site and you will see a picture of what it should look like when done. http://troy.f150online.net/

 

thanks fellas, found the thread on maf and learned that i dont want to do this mod to ive talked to a couple of tunners who know alot more about computer controlled engines and after market add ons. this sounds like it could put you into a lean burn, and with nitrous, I sure dont want to be lean to start with.

 

I does give a lean burn up to about 3500rpm. I found out from the dyno test I had run this summer. They probed the tail pipe during the run. ( my truck felt violated. LOL)
