Probably was running too rich and fouled a plug...

 

Tech and I did notice black tips on my dual exhaust yesterday before the rain.

 

Who did the tunes for you?


I have heard good things about 5 Star tuning. I know a few guys who have them and all are amazed at the work Mike does over there.

 

and I've heard nothing but good things about them yet 2 of the tunes caused my truck to stall and the 93 performance seems to have made my truck run so rich to foul the plug on cylinder six as well as lead to having my entire fuel system flushed out, that is what I assume. Not officially blaming them, just not sure if I will trust any tunes on my F150 now.....never had problems with the mustang
