Questions from a newb...

Hi guys, I have a late 99 f-250 that is bone stock besides a DIY 6637 intake, when i first bought it i went through the entire thing, oil change, fuel filter change, etc. etc...anyway, some things about my truck bug me, sometimes when the truck first starts up and has not fully warmed up it seems to have a ton of power, the engine pulls great, but after the truck warms up a bit it seems to lose that pull and i have to step on it way more to get it going... then at other times the truck is always sluggish like this no matter the temp. When it feels sluggish its like the truck isnt responding to me stepping on the pedal. Could this be a sensor? If so, which one, ICP or MAP?? ( i've seen you guys talking about the icp but cant seem to figure out where it is...)where is it and is there a way to test it? Also I want to put a straight pipe on my truck, I live in Wisconsin and the temps get pretty cold, will this be a issue with the truck or will the stock PCM adjust to the new flow so I dont mess up my engine??

Thanks in advance guys!

Removing the factory muffler is one of the best mods you can do and it will in no way affect the engine, except help it run lower EGT's, but instead of straight piping why not replace it with a Walker BTM, why be illegal? There is little to no difference between EGT temps between a straight piped and a straight shot muffler like the BTM.
As for your sluggish early morning starts this is normal. A diesel should not be worked hard until it comes up to temp, I try and keep my rpm's below 2000 until the gauge starts to come up. If yours is excessive it could be the TPS, throttle position sensor, it is down on the drivers side pedal, spraying some lube on it sometimes frees them up. Congrats on the new truck, I would also get some gauges, do the CCV Mod, change the headlights out to the 03 or 05 style for much more light output. Feel free to PM me with any ?
