That table looks pretty good, though there is a wot spark adder that adds timing to that table I believe. What can you do about the vam pegging? Replace it with a large maf  |

I mean haven't people made like 380 whp with a large vam? I dont think im putting down but 210 to the wheels. I guess since I have 42# injectors I could go with a maf from a lightning.

Those who made big power with the vam would've made much more without the vam. The vam pegs on basically stock engines around 4500rpm or so. Most people are using the 05+ Ford "slot" maf sensors now: cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=390108175025Oh, and your injector size has no influence on what size/style of maf you can run. The idea of a maf being calibrated for a certain injector size is a misnomer created by the Mustang aftermarket. |

You would use a 05+ tube for that sensor correct? Also isn't there a way to change the scaling on the vam voltage ( like raising the peak voltage it sees from 5 v to 5.5v )? I saw some scaling factors in BE and figured that is what they were for.

You don't have to use the factory tube, you can put it in any tube you want.
You can't raise the peak voltage above 5v as that's as high as it can go anyway. You can scale it so the voltage at a given airflow is lower than stock but you'll also need to increase the vam door tension so it takes more airflow to physically open the door all the way. Ultimately this just increases restriction though as the increased spring tension makes the engine work even harder to suck air through the vam.

Well sounds like I will be swapping over to maf as soon as the sensor and tube come in the mail. I know that some wiring is required and some maf trasfering in BE has to be done for this. Hopefully after doing that I will be able to make 300whp with my current setup. Then it will be worthy of ordering some stinger parts. Thank you for all the information stinger!
