Thread: The alt rewire mod actually DOES increase fuel mileage!!

since the install of the alt. rewire and stage 1 volt booster i have notice a .4 miles per gallon increase in gas mileage . i will post up after my next fill up to let you know if it changes any .

I installed the rewire and the stage 1 booster as well... today I filled up to find the actual mileage... +1.2 mpg increase. Not bad at all! Especially at $4.05 a gallon!

I've done some searches and it seems as though some folks have been a bit concerned over this - but if my line of thinking is correct - an additional fuse on the rewire shouldn't be needed, as the stock wire doesn't have a fuse either - correct?

Thanks.

Unless I looked at my GM manual incorrectly this "alt rewire" does bypass a fusible link. fwiw, I still have mine installed w/o a fuse, but have a feeling it's not the smartest thing.
