Hi there

I recently bought a SCT X3 for my 2000 f150 with a 4.6. I ordered it with some custom tunes. The new tunes seem worse than the stock tune. Any ideas as to where I should go from hear? Is this not a good tuner for my truck? Seems like maybe something else is wrong, any ideas?

Thanks

 

You may need to reset the fuel trims in the pcm

First set the truck back to stock

Second disconnect the battery and turn the lights on

Third clean the maf and throttle body and change fuel filter

Forth turn lights off reconnect battery

Fifth go out and drive it 100-150 miles

Sixth now try and program your tune

If the above doesn't work contact the tuner who wrote them.....

Take care

 

Ok thanks, will give it a shot
