I'd agree with him on that. Thing with turning up the fuel is, you gotta do it based on the regular use of the truck and the loads you pull with it day in and day out. For instance, when I was hauling cars all over the country, I had my IP turned slightly down, that way I could run pedal to the floor (literally, have you ever heard and IDI scream against the governor at 3800 rpms?) all day long without risking harming the engine. Now I'm out of college and I've moved several times since, so I no longer have my vehicle transportation "contracts", and the current use of my truck is just a daily driver and a parts hauler - since I don't pull anything heavy I can now get away with running a bit more fuel through the IP and the injectors, as it makes for a bit more power without really endangering the engine during its daily use. However this setting now is at the very borderline of complete fuel burn, at my normal cruise conditions in I'm using just as much fuel as the engine gets air for, and even slight uphills cause it to start making haze at the top of the stack. Hitting an 8% grade in OD, no way, could do it before with the fuel turned down, but now I'm putting way too much fuel in the engine for the load conditions big hills create - I just drop a gear and revv higher, that works amazingly good for keeping the exhaust smokeless. So yeah, given what you're using your truck for, I'd say you're near your borderline as well - generally the higher loads you will put on the engine, the more you're risking damage from high EGTs, so if you regularly pull heavy loads then you gotta make sure the EGTs don't go too high too quick, hence the need for keeping fuel delivery down somewhat.

 

yeah but you would probably be only 10-15 hp above stock IDI and way less torque. But hey if the shoe fits! hahaha

 

So regardless of what I do I might want to install a pyro gauge anyways that way I can monitor EGT's when I'm in the mountains, but unless I manage to get the funds to install a turbo, I'll just leave the IP where its at. Might just make some intake mods to increase the air flow slightly so when in the mountains it burns the fuel more effieciently. Thanks for the help guys.

 

This may help you out some.

I did the link wrong, if you goggle it it will come up.

 

Cold air intake can cost as little as $10 - on my truck for instance I just cut the snorkel over the core support and then shoved it between the rad and the core support down low below the level of the driver-side headlight, then connected it to the air cleaner box with an $8 piece of 4" aluminum clothes dryer ducting - works like a charm

Oh yah, that link actually goes like this:

good free intake, k&n filter, and good exhaust is all most engines need. it'll do better with that combo over stock
