Anybody mess with the performance chips for the 8.3 common rail cummins in a 2388. One guy I talked to said he used 25 gallon less fuel in a day. x 6days=150gpwx2.50pg thats $375(estimated) it seems it would pay for itself in one season. As long as it wouldnt hurt the engine. But some hp increase and fuel savings would be nice.
