I recently did the home fix for my overflow valve on my 97. And it made a monster difference in mpg. But here's my question. Before I 'fixed' it i could lay the hammer down and hit 32 #'s now no matter how hard I try I BARELY hit 28 #'s. Is this normal? I am assuming that because I am not dumping fuel anymore that it isn't needing to produce that much boost anymore, is this assumtion correct or could something be wrong?
