Is it time to "chip" the V-10 in an E-450 class C?

Hi, With fuel prices going through the roof, is it time to "chip" the V-10 engine with the idea of saving fuel? RV is from 2004 so a four speed. I do drive 49 mph (78 kph) and do get 8 to 10 MPG...

Thanks to all who opined.

My decision is to leave things as they are. I'm at 121,000 miles. One mass flow air sensor has been the only mechanical failure. All is well.

I don't stomp on anything. However the OEM brakes "eat" rotors as they overheat and warp. I'm on my third set.

The high cost of fuel will curtail long trips--so my RV may never see Florida again (6000 miles round trip).
