Default injectors?

i have 309,000 miles on the truck with origanal injectors. bottom line they neeed replaced. i get 9.8 miles per gallon cuz they are stuck upen warming up my egts and a little rough on the ideal if i nail it then back off. a couple questions.
1 mariean injectors(stock for the boats) 40 to 60 hp gain derect fit and cheap. is it a good chose.
2 will the rv injectors fit in my engine and work withmy stock vp 44 pump? is the line the same size for them ?
3 there is a 40 hp gain on the rv 275 injectorss po(0432193635) witch is the same for the marreans?

ontop of all this can i get a quote from one of our spocers for the best set up on my truck. i will need 2 sets of connector tubes orings and injectors. one for me and one for my little brother.i am open to alot of ideas. i have a stock turbo with a quadzilla so i dont want to cook my truck with a huge injector but i love the idea of a little more power.basicly dont be shy to propose a 100 hp gain or more with a good price.

Anything from the rv275 to a 7x.009 (100hp) injector will be managable. Did you swap out the hy for an hx35? I see your sig says stock hx but your truck being an 01.5 would have the hy35 stock

No he has the HO 6 speed so his would come stock with the HX35 I believe all the way up to 02 the 6 speeds have the HX. But I agree with you empty wallet up to 100hp injector will be just fine with a HX

hi guys,
i have a 1999 dodge 2500 5.9L 24 valve and i am having about a three second delay on the starting once i go to start my truck for the first time that day, then once driving my truck and it warms up i go to start it the second time and it takes about 5-6 seconds till it fires up. at first it was a really bad hesitation, about 10 seconds, but then thinking my batteries were going bad i replaced em and then it still di it so i went ahead and checked my fuel filter and it was BLACK. so i went ahead and replaced my filter and it fired up after about 2 seconds. so then noticing my fuel psi was low and once it fired up it would take a good 5-6 seconds for the fuel psi to reach 18psi at idle. so i went ahead and replaced my lift pump and now im psi is 20-22 at idle and once fired up its already 20 psi. anyways, i am still having trouble with what may be causing my truck to hesitate for a couple seconds before firing up. if it was my main IP had gone out it wouldnt fire up at all right? i was thinking maybe a bad injector, or two. any help wpuld be great
thanks,
daniel
