One question thats always confused me

[sk3322]

ok so a lot of people get aftermarket chips/tuners for their diesel to make them perform better and some offer improved fuel economy. If the performance from these chips/tuners is so great then why don't diesel trucks computers already come equipped with that kind of tuning out of the factory?

The factory builds cars & trucks with the average joe in mind, The average joe dosen't perform regular maintenance at the recommended intervals, and beats their vehicles to death. The factory tends to downtune power levels to save on wear and tear, and keep the average joe from grenading their vehicle. Also, the factory dosent know all the eventual uses of the truck that the customer has in mind, most people arent going to be pulling heavy loads, and or towing huge trailers full of gear, So they tune the truck to provide a balance between power levels, economy, and wear.. even though these are not always the best settings for the consumer, hence the aftermarket steps in to fill the niche.

yea that makes sense. I don't think that I would tune a new diesel because they are pretty fast stock but my 97 is slooooowww and needs a lot of tuning. I hope an 80hp economy setting won't do too much wear and tear on my engine

The tunner does not put any wear or tear on the motor, the right foot is what does it.:burnout

The factory also has to be able to market the vehicles within a particular price range. Believe me, every detail down to the average switch cycle numbers are scrutinized to save pennies. If it isn't necessary, it is deleted. (ALOT of things determine necessary)

+1 for emissions the tree huggers are bad enough without all the diesels produced blowing black smoke.

Yea that's a very good point. I just wish they would have spent a little extra making these things have more hp lol.

I know what you mean, unfortunately the way to achieve more power, ultimately ends up being,,, having very deep pockets and fat wallets.
