low gas mileage
#12
don't worry, i did do the search. actually i was looking at a bunch of threads yesterday about that problem. If i decide to get something done tomorrow instead of sit around and watch football all day, I will get under the hood and check things out.
so what mustang do ya have?

well, looked under the hood today just to check the computer. it has the sticker saying authorized update....great. so much does a tuner help on these trucks if i ordered one? would a canned tune be off since the plenum issue? i didn't get up in the engine bay so i dont know if there is actually a leak but i assume since they updated it, that it probably is blown.

the 01's came with death flash from the factory. mine has a computer printed sticker for the "authorized update".
if you have a leaking plenum, the advanced timing from a tuner of any kind will expose massive pinging. i went through that. 87 tune in with 87 gas - bad ping. 89/92 gas ok, except for the expense. tune removed - no ping. tune back in - bad ping. overall a superchips tune is like a return to stock, and corrects the speedo for large tires, so its ok.
a $40 tps actually helped me more than anything, eliminated what felt like a terrible dead spot in the gas pedal.
i get about 13-14mpg in city and 14-17 highway. do tune up, front o2, etc
