VMP would get my vote

 

Thanks guys, I will check them out! Gotta finish the suspension then I will be on it.

 

You probably have a mechanical issue with the truck , either bad O2 sensor/s or bad or dirty mass air meter , vacuum leak etc, numerous things with the adaptive learning could make a car run differently after a few drive cycles that are not going to be fixed by any tuner and still will not throw a CE light

Your best bet would be to take it back to the dyno shop and let them look the truck over mechanically

 

O2's would throw a code...MAF has been kept clean with every oil change...no vaccum leaks>>believe me I have checked. It run's different everytime I get in it. I am looking for a stock MAF cause the one I have now is not needed and probably my achilles heal.

 

About to burn a vslave at an air fuel.of 10-1,is rich not lean, FYI

 

My bad ... Air fuel was at 15.6 and was corrected to 12.6.

 

Took the Jet performance MAF out today and installed a Mustang MAF calibrated for 19LBS injectors today and returned to stock with the programmer. Seems to have a little better bottum end now. Got to many things going on at once...lol. Gotta finish getting the stuff for the new drop and then getting a new program from VMP.

 

Talked with Justin at VMP and he said go with a stock MAF. Sooo that being said anyone have one for a stock 4.6????

 

Maybe, I'll check over the weekend and let you know.

 

That would be sweet. I found them on ebay but I am leary about aftermarket electronic parts.

 

Rock Auto has remanufactured Motorcraft mafs for about 65 bucks.

 

okay, I'll check it out. Thanks for your help

 

I would buy a new one from Ford and verify that it is the correct one via your vin number, don't care how much it costs. The maf is second only to the front O2's in importance when considering performance and economy.

 

I have one for a 1998 4.6. Just took it off.

 

Needs to be for an 01, But thanks...good looking out
