In Reply to: Re: 4.10 rear to 3.73 or 3.42? would it greatly improve gas mileage with 8.1l? posted by Bryan on March 22, 04 at 07:56:54:
No. My advice is to remove the 93 octane programming. It's not to be used for towing and it gives no better mileage.
3.42 is not a viable option since it never came OEM. Asking for big trouble in the future.
As much as I'm an HP-a-holic, I don't understand why folks buy a 10 MPG vehicle and then tweak it to use 93 Octane. It's kinda' like buying a Vette and removing 50 HP.
