275 injectors

[Big_Daddy_T]

For those of you out there with similarly equiped trucks. Can you tell me what your 0-60 with just the 275s is(w/o powerbraking or such just straight numbers). There doesnt seem to be a dyno up here and my truck feels a bit sluggish. I want to see if its up to par. presently im seeing about a 13 second 0-60(w/o comp on, imo thats a little slow for 275s.

I plan on an injector upgrade in the near future. I want to get all the bugs out first though.

Big_Daddy_T... . That was my 0-60 time stock without the EZ or BHAF.

Sounds like its time to test your fuel pressure. Having just installed a new lift pump I can vouch that you will feel more "seat of the pants power" going from 0 psi to "enough" psi.

Big Daddy - I found a Dyno in Anchorage and Clayton called them. We are trying to pick a good time for a Dyno Days... . the only drawback is that its going to run about $200 a truck. The guy usually charges $300 for a Diesel but said if we got 5 together he would cut us a deal. If you want the info shoot me a pm.

fuel pressure

My fuel pressure is fantastic. I just removed the prime loc. I have a new lift pump,iat,map,coolant temp. What should I do next? I had the pnp on for a long time with terrible mileage that i just put up with. I thought of it like if you want to play you got to pay. Now I have the comp and mileage is much improved but still laggin on power w/ the box off. Not cool. My freinds 245 ho will eat my 275'd truck for breakfast and he spends alot of time off turbo i dont. Im spinning 30# of boost just on the injectors. I can hit and hold 40# going up and onramp onto the freeway w/the comp on 5x5. So why is it a dog w/the injectors.

Hey Big Daddy T, I will take those horrible 275's off of your hand. That has got to be your problem. I would make you a good offer.

Did you happen to check the tightness of your intercooler boot clamps?? Tightening these will likely help your power concern if not fix it. . If they are too loose, the boots can blow off quite easily at the boost you are running. you may also experience a high pitch whistle under load. . Food for thought. . Garth
