in already running a 75 shot and it just doesnt hit like i want it. the kit i ordered came with jets for a 125 shot. the kit cam with a new fuel pump that works at 80-85 psi. i want to no if i can just switch the jets out and run go, or if i need to do anything else. the kit numbers are 05176NOS and 05176TBNOS. the kit originaly came with the 125 hp jet but i went down cuz i didnt no if my engine could take it so im asking you guys and i hope you can help. its a 95 lt1 engine. thanks for your time

 

come on guys help me out i need to know so i can have them switched to run sat. night

 

Engine should be able to take a 125....did you change to one step colder plugs, just to be safe? Do you have any kind of tuning to advance your timing (because if so, I'd be weary)....

If you don't have added timing, you runon premium, and you put in plugs....put the 125 pill in and go. I noticed you used jet(S)....it is a dry kit, right?

yes it is a dry kit...the LT1 kits use a second jet to control how much vaccuum is pulled on the fuel pressure regulator. The kit is sprayed behind the MAF and relies on an increase of fuel pressure to add the extra fuel.

If you have taken the neccassary safety precautions you should be fine.....but we know very little about your specifics.

 

the nozzle is after the maf so its like 3 inches front the throttle body. the kit came with a fuel pump to work at 85psi and a jet for 125hp so im just gunna guess its ok. i might just go to a local shop and see what they think but if you guys no i will just switch em and run it
