super disappointed in my 7.3

Found out i have a E99. Got back from hauling a toy hauler (yes HEAVY) n was extremely disappointed in the performance from the stock setup. Was planning on doing the 6637 filter mod n exhaust (6.0 trans cooler n ts,jet or dp chip), but not sure it is going to give me desired results! Im not looking for 600hp... like to get 300ish hp n higher torgue numbers just for pulling! Hated going up a long grade at 35mph in second gear!!!!!!!! May just put it up for sale n move on. 99 f250 auto ccsb stock everything 155000miles.

also Wanted to do a lift kit, but found out my 99 lift wont work because it is 99.5 n up pro comp....grrrr only can find a 4" lift. does this also mean my bolt pattern is 8x6.5 instead of 8x170? Argh!!!!
Any input?
just pissed off right now....

Re: super disappointed in my 7.3

welcome, i think you need to relax and do some more research for yourself. i have a e99 that tows 25k regularly with egts under 1100 all day long and pedal to go up anygrade and hill,and not to mention its around 500rwhp. These trucks stock are the worse and yes your lift kill will work.

Re: super disappointed in my 7.3

my first guess would be small worn out injectors...that'll suck the life out of it. second possibly a plugged up cat.

Re: super disappointed in my 7.3

ok... deep breath..... they are stock injectors but recently replaced...
Cat could be plugged... any way to check?
Ideas on mods Jbolen323? advice?
Guessing exhaust... what to do with turbo? 6637 filter mod n exhaust (6.0 trans cooler n ts,jet or dp chip)? Thoughts?

No cats on any 99. I have an e99 with 258K that tows my 16K pound boat and 14K 5th wheel like a dream. Only mods are K&N air filter and straight through 4" exhaust. Now stopping is another story all together. Went through lots of pads until a tried Hawks. They are really awsome. Big difference in stopping ability.

7.3's and 6.0's are like dinosaurs stock. Add 15,000 lbs to the back and it becomes a nightmare. Add an intake and 4" exhaust, and throw a chip in (check out do tuner - always loved them on 7.3's) wnd I think you'd have what you wanted.

Something is probably wrong with the truck, and e99 trucks did have cats.
